Reliable XT1 and RCD Integration for Modular Switchboards
Low-voltage electrical distribution switchboards require properly coordinated circuit breaker mounting arrangements to accommodate switching, overcurrent protection and, where specified, residual current protection. The installation configuration must correspond to the selected breaker frame, pole arrangement and associated protection accessories.
The ABB PHBX1423 is designed for horizontal installation of a 4-pole fixed Tmax XT1 circuit breaker with an RCD arrangement in a compatible 400 mm-wide System pro E Power enclosure section. This defined configuration helps electrical panel builders select the appropriate mechanical installation accessory for the intended assembly.
Residual current protection is used to detect current imbalance associated with earth leakage faults. However, the actual residual current operating characteristics, sensitivity and protection functions depend on the separately selected compatible RCD equipment and circuit breaker combination. The PHBX1423 installation kit does not itself perform residual current detection or circuit interruption.
For correct integration, the breaker, residual current protection equipment, mounting components and enclosure arrangement must be checked against the applicable ABB documentation. Electrical clearances, cable connections, equipment accessibility and the completed assembly's protection characteristics should be assessed during switchboard design and installation.

Frequently Asked Questions
What is the ABB PHBX1423 used for?
The ABB PHBX1423 is an installation kit for a compatible 4-pole fixed ABB Tmax XT1 circuit breaker with an RCD arrangement. It is designed for horizontal installation within a 400 mm-wide ABB System pro E Power switchboard section.
Which circuit breaker is compatible with the ABB PHBX1423?
The PHBX1423 is specified for the ABB Tmax XT1 4-pole fixed circuit breaker configuration with compatible residual current protection equipment. The exact breaker and RCD combination should be verified against ABB technical documentation.
What does RCD mean in the PHBX1423 specification?
RCD stands for Residual Current Device. It refers to equipment used for detecting residual current associated with earth leakage faults. The PHBX1423 supports the specified installation arrangement but does not independently provide residual current protection.
What switchboard width is the ABB PHBX1423 designed for?
The PHBX1423 is specified for a 400 mm-wide ABB System pro E Power switchboard section. This identifies the intended enclosure configuration rather than necessarily representing the physical width of the installation kit.
Does the ABB PHBX1423 include a circuit breaker or RCD?
The PHBX1423 is identified as a circuit breaker installation kit, not a complete protective device assembly. The inclusion of a circuit breaker or RCD is not established by the supplied specification, so the required components and kit contents should be confirmed against ABB ordering documentation.
