Horizontal ABB Tmax XT4 Plug-In Integration for Modular Switchboards
Moulded case circuit breakers are widely used in low-voltage electrical distribution systems to provide circuit protection when selected and configured for the application. Their integration into modular switchboards requires appropriate mounting arrangements, electrical connections, operating clearances and compatibility with the surrounding enclosure structure.
The ABB PHBX4407 is specifically identified as an XT4 kit for 3-pole and 4-pole plug-in circuit breakers, with a horizontal installation orientation and a 400 mm enclosure width. These characteristics distinguish it from kits intended for fixed, withdrawable or differently oriented circuit breaker arrangements.
Plug-in circuit breaker systems use a compatible connection and mounting arrangement that differs from a conventional fixed installation. The PHBX4407 is intended to support the specified XT4 plug-in configuration within the System pro E power platform, subject to the correct selection of the circuit breaker, plug-in components and associated switchboard accessories.
The ABB System pro E power platform includes modular enclosure structures, internal mounting systems, cover panels and dedicated installation kits for compatible electrical distribution equipment. The PHBX4407 forms part of this coordinated system, supporting consistent component selection during professional switchboard design and assembly.
The PHBX4407 is an installation kit, not a complete Tmax XT4 circuit breaker or a complete plug-in connection assembly. The precise supplied components, supported XT4 variants, connection accessories and mounting instructions should be confirmed against the relevant ABB documentation. No independent current rating, breaking capacity or electrical protection function is assigned to this installation kit.
Typical Applications
- ABB System pro E power low-voltage switchgear assemblies.
- Horizontal installation of compatible ABB Tmax XT4 plug-in circuit breakers.
- 3-pole XT4 plug-in circuit breaker arrangements.
- 4-pole XT4 plug-in circuit breaker arrangements.
- Compatible 400 mm wide electrical distribution enclosure sections.
- Industrial power distribution switchboards.
- Commercial building low-voltage distribution cabinets.
- Professional switchgear manufacturing, panel building and compatible equipment refurbishment.
