Reliable Circuit Breaker and Residual Current Protection Integration
Low-voltage electrical distribution cabinets require appropriately matched mounting arrangements to accommodate circuit breakers and their associated protective devices. The ABB PHCX4423 provides a dedicated installation solution for compatible Tmax XT4 fixed 4-pole circuit breakers incorporating residual current protection. Its horizontal configuration supports the positioning of protective equipment within suitable System pro E power switchboard structures.
The ABB Tmax XT4 family comprises moulded-case circuit breakers designed for low-voltage electrical circuit protection. Depending on the selected circuit breaker and trip unit, these devices provide protection against overloads and short circuits. When combined with an appropriately selected residual current device, a compatible XT4 assembly can also provide earth-leakage protection according to the characteristics of the installed equipment.
The ABB System pro E power range provides modular enclosure and installation components for commercial and industrial electrical distribution systems. The PHCX4423 supports coordinated switchboard construction by providing an installation kit matched to the XT4 breaker family, fixed 4-pole execution, residual current protection arrangement and 600 mm cabinet width. The kit supports mechanical installation and does not itself provide electrical protection.
Typical Applications
- ABB System pro E power low-voltage distribution switchboards.
- Horizontal mounting of compatible Tmax XT4 fixed 4-pole circuit breakers.

Frequently Asked Questions
What is the ABB PHCX4423 used for?
The ABB PHCX4423 is a horizontal circuit breaker installation kit designed for mounting compatible ABB Tmax XT4 fixed 4-pole circuit breakers with residual current protection inside System pro E power electrical distribution cabinets.
Which circuit breakers are compatible with the PHCX4423?
The PHCX4423 is specified for compatible ABB Tmax XT4 4-pole fixed moulded-case circuit breakers configured with appropriate residual current protection equipment. The exact breaker execution and associated RCD components should be verified before installation.
What cabinet width is the PHCX4423 designed for?
The PHCX4423 is designed for a nominal cabinet width of 600 mm in compatible ABB System pro E power switchboard configurations.
Does the PHCX4423 provide residual current protection?
The PHCX4423 supports the installation of a compatible XT4 fixed circuit breaker and residual current device (RCD) arrangement. The actual residual current protection function is provided by the separately selected protective equipment, not by the installation kit itself.
Does the ABB PHCX4423 include the circuit breaker and RCD?
The PHCX4423 is identified as a circuit breaker installation kit, rather than a complete protective device assembly. Inclusion of the circuit breaker or residual current device is not established by the product designation, so these components should be confirmed separately.
