Why Choose the ABB PHBT5312 T5 Withdrawable Motorised Circuit Breaker Kit?
The ABB PHBT5312 is a dedicated T5 three-pole withdrawable motorised circuit breaker installation kit designed for ABB System pro E Power modular low-voltage distribution switchboards. Engineered for a 400 A horizontal circuit breaker arrangement within a 400 mm wide module, this kit supports the integration of compatible ABB T5 switching and protection equipment into industrial electrical distribution assemblies.
As part of the ABB System pro E Power series, the PHBT5312 provides a purpose-designed installation solution for a three-pole T5 withdrawable motorised circuit breaker configuration. Its modular design helps panel builders organise switchboard layouts, integrate protective devices and maintain consistency across compatible power distribution systems.
Identified by ABB order code 1STQ008408A0000, the PHBT5312 is specified for horizontal mounting and a 400 A rated circuit breaker arrangement. It is particularly suitable for industrial switchboard manufacturers, electrical contractors and panel builders requiring a dedicated installation kit for compatible ABB T5 withdrawable motorised circuit breakers. The kit is an enclosure integration accessory rather than a complete circuit breaker.

Reliable Circuit Breaker Integration for Low-Voltage Switchboards
Low-voltage power distribution switchboards require carefully arranged protective devices and suitable installation accessories to achieve reliable operation, accessibility and maintainability. The ABB PHBT5312 T5 installation kit is designed to accommodate a compatible 400 A, three-pole, withdrawable motorised circuit breaker within the ABB System pro E Power modular switchboard system.
A withdrawable circuit breaker arrangement allows a suitably equipped breaker to be moved between defined operating positions using its compatible withdrawal mechanism. Motorised operation can support electrically controlled switching when the appropriate circuit breaker operating mechanism and control accessories are fitted. The PHBT5312 provides the specified installation arrangement and should not be confused with the breaker, motor operator or protection trip unit themselves.
The horizontal configuration and 400 mm module width help panel builders plan the physical arrangement of compatible T5 circuit breakers within modular distribution boards. Correct integration requires selection of the appropriate circuit breaker, withdrawable equipment, electrical connections and other necessary accessories in accordance with ABB assembly documentation and the complete switchboard design.
