Reliable Tmax T5 Circuit Breaker Integration for Low-Voltage Switchboards
The ABB PHBT5426 provides a dedicated mechanical installation arrangement for integrating compatible 400 A Tmax T5 plug-in moulded case circuit breakers into System pro E Power switchboards. Plug-in circuit breaker configurations use suitable connection assemblies to enable installation and removal of the breaker from its fixed connection arrangement, subject to the appropriate isolation and maintenance procedures.
The kit is intended for horizontal installation of compatible T5 circuit breakers with rotary handle operation. This arrangement supports organised switchboard construction and allows panel builders to coordinate the circuit breaker position with the surrounding modular enclosure components and operating interface.
With its 400 mm nominal switchboard width, the PHBT5426 is suitable for commercial and industrial distribution panels requiring a dedicated mounting arrangement for the specified T5 configuration. The installation kit is a mechanical accessory and does not itself provide circuit protection. The compatible circuit breaker, plug-in connection components, rotary operating mechanism and any additional accessories should be selected according to the complete ABB switchboard configuration.
