Why Choose the ABB PHDX4423 XT4 4-Pole Fixed Circuit Breaker Installation Kit?
The ABB PHDX4423 (1STQ001449B0000) is a dedicated XT4 4-pole fixed circuit breaker installation kit with RCD provision, designed for horizontal installation in compatible ABB System pro E Power low-voltage distribution switchboards. Specified for an 800 mm-wide switchboard arrangement, this accessory supports the integration of ABB Tmax XT4 circuit breakers into modular electrical distribution assemblies.
Part of the ABB System pro E Power range, the PHDX4423 provides a purpose-designed installation solution for applications requiring a fixed-mounted, four-pole XT4 circuit breaker with residual current protection equipment. Its horizontal mounting configuration helps panel builders organise protective devices within the designated switchboard compartment while maintaining compatibility with the intended ABB assembly system.
The PHDX4423 is an installation kit rather than a complete circuit breaker. The appropriate ABB Tmax XT4 breaker, residual current protection equipment and associated electrical connections must be selected according to the installation requirements and verified against ABB compatibility documentation.

Horizontal XT4 Circuit Breaker Integration in Modular Switchboards
The ABB PHDX4423 installation kit is intended for integrating a four-pole, fixed-mounted ABB Tmax XT4 circuit breaker into a compatible System pro E Power switchboard. Its dedicated horizontal installation arrangement helps establish the intended equipment position within an 800 mm-wide switchboard structure.
The kit is specified for an XT4 configuration incorporating RCD equipment. Residual current protection can form part of an electrical installation's protective measures, but the actual protection functions, settings and ratings depend on the separately selected circuit breaker and residual current device. The PHDX4423 itself does not detect residual current, interrupt fault current or provide overload protection.
Correct integration requires checking the compatibility of the selected XT4 breaker, residual current protection arrangement, electrical connections and switchboard components. The completed assembly must be installed in accordance with the applicable ABB instructions and relevant electrical installation and switchboard standards.
Typical Applications
- ABB System pro E Power low-voltage distribution switchboards.
- Horizontal installation of ABB Tmax XT4 fixed circuit breakers.
- Four-pole circuit breaker mounting arrangements.
- Switchboard compartments incorporating residual current protection equipment.
- Industrial electrical distribution panel construction.
- Commercial building power distribution systems.
- OEM switchboard manufacturing and electrical panel building.
- Upgrading or replacing compatible XT4 installation arrangements.
- Electrical infrastructure projects using ABB modular switchboard assemblies.
