Reliable Dual Circuit Breaker Integration for Electrical Distribution Systems
The ABB PHBX4402 installation kit supports the integration of two compatible Tmax XT4 fixed circuit breakers into System pro E power switchgear structures. Its horizontal mounting configuration enables panel builders to organise multiple protective switching devices within a specified 400 mm wide cabinet section.
Fixed moulded case circuit breakers are commonly used in low-voltage distribution systems to provide circuit protection against overloads and short circuits, according to the protection characteristics of the selected breaker and trip unit. The PHBX4402 provides an installation arrangement for these devices rather than performing an electrical protection function itself.
The PHBX4402 is a mounting kit rather than a complete circuit breaker assembly. The required XT4 circuit breakers, trip units, electrical connections and accessories must be selected according to the switchboard design and ABB installation instructions.
Typical Applications
- ABB System pro E power low-voltage switchgear assemblies.
- Horizontal installation of two Tmax XT4 fixed circuit breakers.
- Industrial electrical distribution switchboards.
- Commercial building power distribution systems.
- Electrical distribution cabinets with multiple outgoing circuits.
- OEM switchboard manufacturing and electrical panel building.
- Modular switchgear assemblies using 400 mm wide structures.
- Industrial plant power distribution infrastructure.
- Electrical control and distribution panel construction.
- Professional switchgear assembly and equipment integration.
