Reliable Horizontal XT2 Circuit Breaker Integration
The ABB PHCX2301 horizontal installation kit is designed to support the integration of a compatible fixed ABB Tmax XT2 moulded case circuit breaker into a System pro E power electrical distribution switchboard. Moulded case circuit breakers are widely used in low-voltage installations to provide circuit switching and protection against overloads and short circuits when appropriately selected and configured.
The ABB Tmax XT2 series forms part of ABB's Tmax XT moulded case circuit breaker family. These devices are used in electrical distribution applications where circuit protection, switching functionality and integration with associated accessories are required. The PHCX2301 provides the designated mechanical installation arrangement for a fixed, 3-pole XT2 device rather than serving as the circuit breaker itself.
The kit's horizontal installation configuration is intended for compatible System pro E power switchboard structures with a nominal width of 600 mm. This enables panel builders to plan the position of the circuit breaker within the enclosure and coordinate its installation with suitable connection arrangements, operating components and other electrical distribution equipment.
The ABB System pro E power range provides a modular platform for constructing professional low-voltage switchboards. Its configurable enclosure structures support circuit protection devices, switch-disconnectors, busbar systems and dedicated installation accessories. The PHCX2301 complements this system by providing a specific mounting solution for the stated Tmax XT2 configuration.
Correct installation requires the selection of a compatible fixed 3-pole XT2 circuit breaker and the appropriate System pro E power enclosure components. Mechanical fixing, electrical connections, access to the operating mechanism, required clearances and any additional accessories should be checked against the relevant ABB installation instructions. The complete low-voltage switchboard should be designed and verified in accordance with applicable IEC 61439 requirements.
Because the PHCX2301 is an installation accessory rather than a protective switching device, it does not independently determine the circuit breaker's current rating, breaking capacity, trip unit characteristics or protection settings. These electrical specifications depend on the separately selected ABB Tmax XT2 circuit breaker and the overall switchboard design.
