Multi-Circuit Power Meter
PA60 Multi-Circuit Power Meter
The PA60 is a compact multi-circuit, multi-function power meter designed for single-phase and three-phase electrical measurement. It is suitable for applications where multiple circuits must be monitored from one compact metering device, reducing panel space, wiring effort and overall monitoring cost.
With support for multiple wiring configurations, clip-on external CTs, wide current measurement range and built-in communication, the PA60 is well suited for retrofit energy monitoring, distribution board metering, sub-metering, tenant metering and electrical load visibility in industrial and commercial installations.
Meter Type
Multi-circuit power and energy meter
Maximum Channels
Up to 12 single-phase or 4 three-phase circuits; expandable
CT Support
External clip-on CTs from 5A up to 500A
Communication
Built-in dual RS485 ports; optional RS485 or Ethernet module
Description
The PA60 is designed for general single-phase and poly-phase power measurement. It can be applied on low-voltage primary-side installations or on medium-voltage and high-voltage secondary metering points when used with suitable CT and VT arrangements.
Its multi-circuit architecture makes it practical for applications where many feeders, tenants, floors, machines or distribution board circuits must be monitored from one device. The meter supports True RMS measurement and provides key electrical values required for energy monitoring, load analysis and basic power management.
Best use case: PA60 is especially suitable for retrofit sub-metering projects where many outgoing feeders must be monitored without installing one individual meter for every circuit.
Key Features
Multi-Circuit Measurement
Supports up to 12 single-phase circuits or 4 three-phase circuits in the base configuration, with expansion capability up to 24 single-phase or 8 three-phase circuits.
True RMS Measurement
Measures key power and energy parameters accurately in compact form for electrical distribution monitoring.
Retrofit-Friendly CTs
Supports external clip-on CTs from 5A up to 500A, making installation easier in existing panels.
Flexible Wiring Modes
Supports multiple wiring configurations including 3P3W, 3P4W, 1P2W, 1P3W and mixed single-phase / three-phase arrangements.
Per-Channel Configuration
Each channel can be configured flexibly, allowing different circuits and wiring arrangements to be managed from one device.
Dual RS485 Ports
Built-in dual RS485 communication ports support integration into monitoring systems, gateways, EMS, BMS, SCADA or IoTWatt 4.0.
Optional Communication Module
Optional RS485 or Ethernet module can be added depending on the project communication architecture.
Compact Design
Small form factor helps reduce panel space compared with multiple individual meters.
Cost-Effective Sub-Metering
Ideal for applications where many circuits need to be monitored economically.

Typical Applications
Distribution Board Sub-Metering
Monitor many outgoing feeders from one meter instead of installing multiple individual power meters.
Tenant and Floor Metering
Measure energy consumption by tenant, floor, department, zone or rental area.
Industrial Load Monitoring
Track pumps, motors, compressors, HVAC circuits, production feeders and general equipment loads.
Retrofit Energy Monitoring
Clip-on CTs reduce installation complexity in existing panels where shutdown time must be minimised.
Energy Audit Measurement
Provides circuit-level data for identifying major energy users and analysing load patterns.
IoTWatt 4.0 Integration
Use multi-circuit metering data for dashboards, cost allocation, energy audit analytics and EECA reporting support.
Typical System Architecture
PA60 meters can be connected to multiple CTs installed on outgoing feeders. The measured values can be transmitted through RS485 or Ethernet to a gateway, EMS, BMS, SCADA or IoTWatt 4.0 for centralised monitoring and reporting.
Integration with IoTWatt 4.0
When integrated with IoTWatt 4.0, the PA60 becomes a practical multi-circuit data source for digital energy audit, tenant metering, feeder comparison, load profiling, abnormal consumption detection and energy savings verification.
- Monitor multiple single-phase or three-phase circuits from one device.
- Compare energy consumption between feeders, tenants, departments or production areas.
- Identify major energy users and abnormal load patterns.
- Use circuit-level data for energy audit baseline development.
- Support EECA reporting and continuous energy performance monitoring.
- Connect through RS485 or Ethernet depending on the selected communication option.
Integration note: For IoTWatt 4.0, the PA60 can be connected through RS485 using a suitable gateway such as RS2LAN, RS2MQTT or RS2WLAN, or through Ethernet where the optional Ethernet communication module is installed.
Recommended Deployment Checklist
- Confirm the number of single-phase and three-phase circuits to be monitored.
- Confirm whether base capacity is sufficient or expansion is required.
- Confirm wiring mode for each circuit.
- Confirm CT rating required for each feeder, from 5A up to 500A.
- Confirm panel space, CT installation clearance and cable routing.
- Confirm communication requirement: RS485 or Ethernet.
- Confirm Modbus address, baud rate, parity and register mapping if RS485 is used.
- Confirm EMS, BMS, SCADA, gateway or IoTWatt 4.0 integration requirement.
- Test CT direction, voltage reference, phase mapping and communication during commissioning.
