In power distribution retrofits and new projects, engineers often face a dilemma: achieving high-precision energy and power quality monitoring for three-phase circuits while being constrained by limited panel cutout space and complex wiring conditions. Traditional three-phase meters tend to be bulky, have fixed connections, and lack flexibility in current sensor selection—Rogowski coils, voltage-output CTs, and conventional 5A CTs often require different hardware versions, leading to lengthy selection processes and high inventory costs.

The Roc337 is a standard 96×96mm panel-mount three-phase multi-function energy meter, designed for industrial power distribution, energy monitoring, and power analysis. It features snap‑on tool‑free installation, supports direct connection to Rogowski coils, voltage‑output CTs, and 5A CT inputs, offers multiple power supply options, and integrates advanced functions such as harmonic analysis, demand calculation, and multi‑tariff energy. One meter meets the majority of low‑voltage and medium‑voltage metering applications.

Three Core Advantages: Simplify Complexity

1. Flexible Current Sensor Compatibility – One Model for All Scenarios

The Roc337 is available in two sub‑series: Type N (Rogowski coil and voltage-output CT) and Type C (5A/7A conventional CT input). This means:

• Retrofit projects: No power shutdown or rewiring required – simply clamp the Rogowski coil around cables or busbars, reducing installation time by over 80%.
• New installations: Freely choose sensors according to current range, covering from 5A up to 12,000A.

Typical Applications

1. Low‑Voltage Switchgear – Incomer and Feeder Metering

In factory, commercial building and data center LV rooms, the Roc337 mounts directly on cabinet doors or instrument panels. Non‑invasive Rogowski coils (no external integrator needed) avoid disconnecting busbars or cables. Data is aggregated via RS485 to power monitoring systems or EMS.

2. Medium‑/High‑Voltage Substation Secondary Side Monitoring

Using voltage transformers (VTs) and current transformers (CTs), the Roc337 can be safely connected to the secondary side of MV/HV systems. Its wide voltage measurement range and programmable PT/CT ratios (via Modbus) make it ideal for substation smart meter retrofits.

3. Power Quality Analysis for Ports, Mines and Heavy Equipment

Large motors, cranes and VFDs generate significant harmonics and unbalance. The Roc337 provides 1st–50th harmonic monitoring, unbalance and demand analysis – helping maintenance staff detect overload or distortion anomalies before unplanned downtime occurs.

4. Tenant Billing and Sub‑Metering in Commercial Buildings

In today‘s industrial and commercial power distribution systems, the demand for circuit‑level energy monitoring is growing rapidly – yet panel space is becoming increasingly scarce. Traditional metering solutions typically require one meter per circuit, consuming excessive DIN rail space, demanding power shutdowns, complex rewiring, and high installation costs. For retrofit projects, dense distribution panels, or drawer‑type switchgear, these challenges are even more critical.

The Roc132 is a high‑performance energy meter designed specifically for multi‑circuit monitoring. With an ultra‑compact 1P (18mm) width, non‑invasive Rogowski coil or split‑core CT installation, and the ability to cascade multiple units sharing a single voltage reference, the Roc132 allows you to accurately measure dozens of circuits without modifying existing layouts or interrupting power.

Three Core Advantages – Told by Numbers

1. 1P Width – Save 60–80% of DIN Rail Space

Each Roc132 module occupies only 18mm (1P) of DIN rail space, while conventional three‑phase meters typically require 4P to 8P. For a project monitoring 10 circuits, the Roc132 saves over 180mm of rail length – turning an impossible retrofit into a simple installation. For space‑critical applications like drawer‑type switchgear or prefabricated substations, this is often the only feasible solution.

2. Non‑Invasive Installation – Reduce Labor Cost by >60%

The Roc132 works with flexible Rogowski coils (100A to 6000A) or split‑core CTs (≤100A). These sensors can be clamped directly onto cables, copper bars, or busbars – no circuit disconnection, no busbar removal, no power shutdown. Retrofits can be completed while production lines keep running, eliminating downtime, reducing electric shock risks, and cutting installation time to one‑third of conventional methods.

3. Cascading Design – One Voltage Connection for Dozens of Circuits

When multiple Roc132 meters are mounted side by side, a simple MC cascading component transmits the voltage reference (L1/L2/L3/N) and the RS485 bus from one meter to the next. This means: no matter how many circuits you monitor, you only need to connect voltage wires once. No more parallel wiring for each meter, no more dozens of terminal blocks – wiring errors approach zero.

Key Specifications – What the Numbers Mean for You

Communication	RS485 Modbus‑RTU	Plug‑and‑play integration with PLCs, SCADA, gateways, and energy management systems

Typical Applications

Drawer‑Type Low‑Voltage Switchgear

Space inside drawer compartments is extremely limited, making traditional meters impossible to install. The Roc132’s 1P width fits easily on the rear panel or side plate, while flexible Rogowski coils clamp directly onto the primary busbars – no disassembly required. Multiple drawers share a single voltage reference via the cascading component, and all data is collected centrally over RS485. This is currently the most space‑efficient drawer monitoring solution available.

Production Line Machine Monitoring

An automated production line typically includes rotary tables, lifts, conveyors, robots, and other workstations. Install one Roc132 per machine, cascade them along the DIN rail, and connect voltage only once. Real‑time current, power, and energy data flow into the PLC or MES via Modbus, helping production managers identify inefficient equipment, optimize cycle times, and calculate product‑level energy costs.

Commercial Building Sub‑Metering

In floor‑level distribution rooms, circuits for lighting, HVAC, elevators, general outlets, and fan coils need separate measurement. The Roc132’s small footprint allows retrofitting inside existing panels without any enclosure modification. The 51st‑order harmonic measurement also helps diagnose neutral overheating or transformer issues caused by non‑linear loads such as VFDs and LED drivers.

Data Center PDU Monitoring

Data centers demand continuous operation and maximum space utilization. The Roc132, paired with flexible Rogowski coils, can be added to PDU input or output busbars without any power interruption. Class 0.5S accuracy provides trustworthy data for PUE calculation, the cascading design reduces internal wiring clutter, and RS485 output integrates seamlessly with DCIM software.

Quality and Reliability

The Roc132 is designed and manufactured to meet IEC 61557‑12 (performance class PMD‑II/DD/K70/1) and carries CE certification. Key reliability features include:

• Measurement category CAT IV – suitable for distribution side applications
• Pollution degree 3 – designed for industrial dust environments
• Wide operating temperature (-25°C to +70°C) – no concerns about high temperatures inside electrical panels
• Factory full‑range calibration – guaranteed 0.5S accuracy over the entire current range

In modern industrial automation, power quality monitoring, and renewable energy systems, accurate current measurement is the foundation of efficiency, protection, and data‑driven decision‑making. Traditional current transformers (CTs) often struggle with magnetic saturation, limited bandwidth, bulky size, and difficult installation – especially in retrofit projects or high‑current scenarios.

Rogowski coils overcome these limitations. Their air‑core design eliminates saturation, provides a wide frequency response (from a few Hz to MHz), and offers a flexible, lightweight structure that can be installed around existing cables without interrupting power. This makes them the preferred choice for engineers and system integrators worldwide.

We offer three Rogowski coil series – WRC, RV, and RN-XL – each engineered for a specific class of applications. Below is a detailed look at what makes each series unique and how to choose the right one for your project.
