Reliable Circuit Breaker Integration for Low-Voltage Distribution Systems
The ABB PHCX4402 is designed to support the installation of compatible ABB Tmax XT4 moulded-case circuit breakers within System Pro E Power electrical distribution assemblies. Tmax XT4 circuit breakers are used for electrical circuit protection, including overload and short-circuit protection, depending on their selected trip units, current ratings and application requirements.
The PHCX4402 provides a dedicated installation arrangement for two XT4 fixed circuit breakers, helping electrical panel builders organise protective devices within a 600 mm-wide switchgear compartment. Unlike plug-in or withdrawable circuit breaker arrangements, fixed installations use a stationary mounting configuration with electrical connections appropriate to the selected breaker and switchgear design.
The ABB System Pro E Power platform supports modular low-voltage switchboard construction, including assemblies designed in accordance with IEC 61439-2. The PHCX4402 is an installation accessory rather than a complete protective device. Compatible XT4 circuit breakers, electrical connections and any additional assembly components must be selected according to the intended switchgear configuration and ABB installation requirements.
Typical Applications
- ABB System Pro E Power modular switchgear assemblies.
- Installation of two compatible ABB Tmax XT4 fixed circuit breakers.
- Industrial low-voltage power distribution cabinets.
- Main electrical distribution boards and sub-distribution panels.
- Commercial electrical distribution switchboards.
- Fixed moulded-case circuit breaker installation arrangements.
- OEM electrical panel building and switchgear manufacturing.
