1TVS151800S3340 ABB EPX-METER125-SP Protecta Power 125A Single-Phase M4M Pulse Modbus Outgoing Metering Kit

Why Choose the ABB EPX-METER125-SP 125A Single-Phase Metering Kit?

The ABB EPX-METER125-SP is a dedicated 125 A single-phase outgoing metering kit for compatible ABB Protecta Power electrical distribution assemblies. Part of the ABB Protecta Power Enclosures product group, this kit provides an integrated approach to monitoring electrical consumption on individual outgoing circuits. Identified by ABB order code 1TVS151800S3340, the product is described as the EPX-METER125-SP 125A M Kit - 1Ph P+M.

Designed around ABB's M4M energy metering technology, the EPX-METER125-SP supports single-phase electrical measurement with pulse output and Modbus communication capabilities. This makes it suitable for distribution installations where energy consumption information needs to be collected for building management, operational monitoring or electrical energy analysis.

The kit includes the meter, fixing brackets, current transformer (CT) and terminals required for its specified metering arrangement. It is designed for installation in a compatible Protecta Power side extension enclosure with metering provision, which must be ordered separately. This coordinated arrangement helps electrical contractors and panel builders incorporate outgoing circuit monitoring into commercial and industrial distribution systems.

Single-Phase Energy Monitoring with Pulse and Modbus Communication

The ABB Protecta Power system provides a modular platform for low-voltage electrical distribution, with outgoing metering accessories that allow individual circuits to be monitored. The EPX-METER125-SP is intended for a 125 A single-phase outgoing circuit application, providing a dedicated metering solution rather than relying on a separately assembled collection of unrelated components.

The kit uses an ABB M4M meter with pulse and Modbus capabilities. Pulse outputs can be used with compatible equipment to collect energy consumption information, while Modbus communication provides a means of exchanging measurement data with suitable monitoring or building management systems. The available measurements, communication settings and connection requirements depend on the meter supplied and its applicable ABB documentation.

ABB specifies that its Protecta Power outgoing metering kits include a meter, fixing brackets, CT and terminals. The current transformer enables current measurement as part of the metering arrangement, while the supplied mechanical and connection accessories support integration into the designated enclosure system. A side extension box with metering provision is required and must be ordered separately; the EPX-METER125-SP should not be treated as a complete standalone enclosure assembly.

For installations requiring a different metering configuration, ABB offers the EPX-METER125MID-SP single-phase kit with an MID-designated meter option and the EPX-METER125-TP three-phase outgoing metering kit. The standard EPX-METER125-SP is identified as the pulse / Modbus version, so MID approval should not be assumed for this model. The correct kit should be selected according to the circuit configuration, metering purpose and applicable project requirements.
