ABB 1STQ008420A0000 PHBX4431 System Pro E Power horizontal installation kit for two compatible ABB Tmax XT4 three-pole or four-pole plug-in moulded case circuit breakers in a nominal 400 mm wide low-voltage switchboard section.
£162.22
The ABB 1STQ008420A0000, also identified as PHBX4431, is a dedicated horizontal circuit breaker installation kit for the ABB System Pro E Power low-voltage switchboard range. It is designed to accommodate two compatible ABB Tmax XT4 plug-in moulded case circuit breakers within a coordinated electrical distribution assembly.
The ABB PHBX4431 supports 3-pole and 4-pole Tmax XT4 plug-in circuit breaker configurations, providing an application-specific mechanical installation arrangement for professional switchboard manufacturers and electrical panel builders. Its horizontal layout helps integrate two compatible circuit breakers into the modular System Pro E Power platform.
Specified for a nominal 400 mm wide switchboard section, this kit is identified by the ABB designation 2 XT4 KIT 3-4P PLUG IN I HORIZ. W=400MM. It is an installation accessory rather than a complete circuit breaker assembly, making it suitable for projects where compatible switching and protection devices are selected separately.
The ABB PHBX4431 installation kit provides a dedicated mechanical arrangement for positioning two compatible Tmax XT4 plug-in moulded case circuit breakers in a System Pro E Power switchboard. The horizontal configuration is intended to support an organised layout within the specified nominal 400 mm wide section, while the selected breakers provide the electrical switching and protection functions.
Plug-in circuit breakers use compatible connection bases to interface with the electrical installation. The appropriate Tmax XT4 breaker versions, plug-in bases, connection components and any other necessary accessories must be selected to match the complete switchboard design. The PHBX4431 is a mounting kit and does not independently provide circuit protection, current switching or a rated electrical connection.

The ABB PHBX4431 is a horizontal installation kit designed to accommodate two compatible ABB Tmax XT4 plug-in moulded case circuit breakers within System Pro E Power low-voltage switchboard assemblies.
The kit is specified for compatible ABB Tmax XT4 plug-in circuit breakers in 3-pole and 4-pole configurations. The exact breaker executions, plug-in bases and additional accessories must be checked against the relevant ABB installation documentation.
The product designation identifies an installation arrangement for two ABB Tmax XT4 circuit breakers in the specified horizontal configuration.
The PHBX4431 is specified for a nominal 400 mm wide switchboard section within the ABB System Pro E Power range. This is a switchboard configuration dimension rather than a confirmed overall physical dimension of the kit.
The ABB 1STQ008420A0000 is an installation kit, not a complete circuit breaker assembly. The compatible Tmax XT4 circuit breakers, plug-in bases and other required electrical accessories should be selected separately according to the installation requirements.
ABB System Pro E Power accessories support coordinated low-voltage switchboard construction for professional electrical panel builders. The PHBX4431 horizontal installation kit provides a dedicated arrangement for two compatible Tmax XT4 plug-in circuit breakers, helping integrate circuit protection equipment into modular electrical distribution assemblies.
