Reliable XT4 Circuit Breaker Integration for Low-Voltage Switchboards

The ABB System pro E power range provides a modular platform for constructing low-voltage electrical distribution switchboards. Dedicated circuit breaker installation kits such as the PHBX4425 enable compatible protective devices to be arranged within the switchboard structure according to the required installation configuration.

The PHBX4425 is specifically identified for two Tmax XT4 circuit breakers in a horizontal withdrawable arrangement. This configuration supports accessible equipment layouts and helps simplify maintenance planning where withdrawable circuit breaker installations are specified.

ABB Tmax XT4 moulded case circuit breakers are used for electrical circuit protection in low-voltage distribution systems. When incorporated into a correctly designed System pro E power assembly, the PHBX4425 provides the installation arrangement for compatible XT4 devices. Circuit breaker ratings, electrical connections and any additional mounting accessories must be selected according to the complete switchboard design.
