Reliable Circuit Breaker Integration for Industrial Power Distribution
Correct circuit breaker mounting is essential for the mechanical integrity, accessibility and maintainability of low-voltage electrical distribution assemblies. Dedicated installation kits help ensure that protective devices are positioned consistently within switchboard compartments, supporting effective panel construction and straightforward integration with the surrounding enclosure structure.
The ABB PHBX3305 provides a dedicated horizontal mounting solution for fixed three-pole Tmax XT3 circuit breakers equipped with direct rotary handles. The installation arrangement incorporates fixing brackets, a mounting plate and front panels secured using quarter-turn fasteners. These components help panel builders achieve an organised installation while providing suitable access to the circuit breaker operating interface.
The kit is intended for compatible 400 mm wide System pro E Power switchboard structures. Installation must follow ABB's assembly instructions, including the appropriate selection of internal support components and enclosure arrangements. In compatible non-segregated structures, fixed XT3 circuit breakers with direct rotary handles can be installed without additional intermediate depth uprights, subject to the specified switchboard configuration.
Typical Applications
- ABB System pro E Power low-voltage switchboards.
- Horizontal installation of fixed three-pole Tmax XT3 circuit breakers.
- Main electrical distribution boards.
- Industrial power distribution panels.
- Commercial building electrical distribution systems.
- Electrical control and protection cabinets.
- OEM switchboard manufacturing and panel building.
- Power distribution equipment in manufacturing facilities.
- Switchboard assembly, refurbishment and compatible mounting kit replacement.
