Horizontal XT3 Plug-In Circuit Breaker Installation for Modular Switchboards

Plug-in moulded case circuit breakers are used in low-voltage electrical distribution systems where circuit protection is combined with a removable breaker connection arrangement. Unlike fixed-mounted configurations, plug-in circuit breakers connect to compatible fixed connection components, allowing the breaker to be removed according to the manufacturer's prescribed isolation and safety procedures. This arrangement can support planned maintenance and equipment replacement when the complete installation is correctly specified.

The ABB PHBX3407 is specifically intended for the horizontal installation of 3-pole or 4-pole Tmax XT3 plug-in circuit breakers within compatible 400 mm-wide System pro E power modules. Its dedicated mounting configuration supports the integration of suitable XT3 devices into modular switchboard structures, helping electrical panel builders achieve a consistent and organised installation layout.

The ABB Tmax XT3 belongs to ABB's Tmax XT moulded case circuit breaker family, developed for low-voltage circuit protection and switching applications. Plug-in XT3 configurations require compatible breaker executions and connection components. The PHBX3407 is intended to form part of this wider installation arrangement rather than function as a standalone protective device.

The ABB System pro E power range provides a modular platform for low-voltage switchboard construction, allowing panel builders to combine compatible enclosure structures, circuit breaker installation kits and electrical distribution components. The PHBX3407 is an installation kit, not a complete circuit breaker. The exact kit contents, compatible breaker variants, required plug-in components, electrical clearances and mechanical installation requirements should be confirmed against the relevant ABB technical documentation for the complete assembly.
