1TVS151800S3342 ABB EPX-METER125-TP 125A Three-Phase Outgoing Metering Kit M4M Pulse Modbus Protecta Power

Why Choose the ABB EPX-METER125-TP 125A Three-Phase Metering Kit?

The ABB EPX-METER125-TP, manufacturer order code 1TVS151800S3342, is a dedicated 125 A three-phase outgoing metering kit for compatible ABB Protecta Power electrical distribution panelboards. Identified by ABB as the EPX-METER125-TP 125A M Kit - 3Ph P+M, this accessory provides an integrated metering solution for monitoring electrical consumption on suitable three-phase outgoing circuits.

Designed around an ABB M4M multifunction energy meter, the EPX-METER125-TP supports electrical measurement and communication through pulse output and Modbus connectivity. It is intended for applications where electrical contractors, panel builders and facility managers need visibility of individual distribution circuits rather than relying solely on incoming supply measurements.

The kit includes the meter, fixing brackets, current transformers (CTs) and terminals required for its designated metering arrangement. ABB specifies that a compatible side extension box with metering provision must be ordered separately, making the EPX-METER125-TP a metering accessory kit rather than a complete standalone enclosure.

As part of the ABB Protecta Power Enclosures product group, the EPX-METER125-TP supports professional low-voltage distribution assemblies in commercial, industrial and infrastructure installations. Its 125 A three-phase configuration makes it particularly suitable for monitoring compatible outgoing feeders within the ABB Protecta Power MCCB panelboard system.

Three-Phase Outgoing Circuit Metering with ABB Protecta Power

The ABB Protecta Power range provides modular low-voltage MCCB distribution panelboards for commercial and industrial applications. Alongside incoming and outgoing circuit protection, the system supports dedicated metering accessories that allow electrical designers to incorporate measurement and monitoring functions into compatible distribution assemblies.

The ABB EPX-METER125-TP is specifically designated as a 125 A outgoing metering kit for three-phase circuits. Unlike an incoming metering arrangement that monitors the overall supply to a distribution board, an outgoing metering kit is intended to measure the electrical characteristics of a selected downstream circuit.

ABB specifies an M4M Pulse / Modbus meter for this kit. The M4M multifunction meter family supports electrical measurement and energy monitoring applications, while the pulse and Modbus communication options allow measurement information to be integrated into compatible external systems. The precise measurement parameters and communication settings depend on the supplied meter variant and its configuration.

The kit uses current transformers to provide current measurement signals to the meter. ABB's stated pack contents include the meter, fixing brackets, CTs and terminals, providing the principal components for the designated outgoing metering arrangement. The current transformer installation, wiring, meter supply and commissioning must follow the applicable ABB documentation.

A key installation requirement is the side extension box with metering provision. ABB explicitly states that this enclosure must be ordered separately for outgoing metering kits. The side extension provides the appropriate location for the metering components within a compatible Protecta Power panelboard assembly.

ABB also offers other outgoing metering kit ratings, including 160–250 A, 400 A and 630 A three-phase options. These allow electrical designers to select a metering kit appropriate to the designated outgoing circuit rather than using the 125 A version for every application.

For applications requiring an explicitly MID-designated product, ABB separately lists the EPX-METER125MID-TP. The EPX-METER125-TP is the standard M4M Pulse / Modbus variant and should not be represented as MID-approved solely on the basis of its model designation. Where metering is required for billing or other regulated purposes, the appropriate meter certification and installation requirements must be verified.

The EPX-METER125-TP is a metering kit, not a circuit protection device. It does not replace the MCCB or other protective equipment required for the outgoing circuit. The completed installation must incorporate suitable electrical protection, correct current transformer connections, appropriate meter supply arrangements and any required communications wiring.
