Why Choose the ABB PVBX4401 XT4 Fixed Circuit Breaker Installation Kit?
The ABB PVBX4401 (1STQ007960A0000) is a dedicated Tmax XT4 fixed circuit breaker installation kit from the ABB System pro E Power range. Designed for compatible three-pole and four-pole ABB Tmax XT4 moulded case circuit breakers (MCCBs), this kit supports vertical installation within a 400 mm wide low-voltage switchboard arrangement.
Part of the ABB System pro E Power modular switchboard system, the PVBX4401 provides a purpose-designed mechanical mounting solution for integrating compatible fixed-mounted Tmax XT4 circuit breakers into electrical distribution assemblies. It is intended for professional switchboard manufacturers, electrical contractors and panel builders requiring an installation arrangement matched to the selected circuit breaker and switchboard configuration.
The manufacturer's designation, XT4 KIT 3-4P FIXED VERT.INST. W=400MM, identifies the principal installation requirements: ABB Tmax XT4 compatibility, three-pole or four-pole construction, fixed mounting, vertical installation and a nominal switchboard width of 400 mm.
The ABB PVBX4401 is a mechanical installation accessory rather than a complete circuit breaker assembly. It supports the physical integration of a compatible protective device into a System pro E Power switchboard, while electrical protection and switching functions are provided by the separately selected circuit breaker.

Reliable Circuit Breaker Integration for Low-Voltage Power Distribution
The ABB PVBX4401 is intended for switchboard designs where a compatible fixed-mounted Tmax XT4 circuit breaker must be installed vertically within a 400 mm wide System pro E Power arrangement. Its support for both three-pole and four-pole configurations allows panel designers to select the appropriate pole arrangement while using a mounting kit specified for the corresponding installation requirements.
A fixed circuit breaker installation uses a non-withdrawable mounting configuration. Unlike plug-in or withdrawable circuit breaker arrangements, a fixed-mounted breaker is not designed around a dedicated plug-in or racking connection system. The PVBX4401 should therefore be selected for the fixed version of the compatible Tmax XT4 circuit breaker.
The vertical installation designation is particularly important when planning the physical arrangement of components inside a distribution switchboard. Panel builders must consider the selected circuit breaker, electrical connections, operating clearances and other installed equipment when confirming the overall layout.
The manufacturer's description for 1STQ007960A0000 does not specify a rotary handle drive, motor operator or particular interlocking arrangement. Any such requirements should be established separately using the selected Tmax XT4 circuit breaker configuration and the applicable ABB technical documentation.
The ABB PVBX4401 is a mechanical installation accessory. It does not independently provide circuit protection, electrical switching or a complete operating mechanism. The supplied kit contents, compatible Tmax XT4 variants and any additional mounting or connection components should be confirmed against ABB documentation before installation.
