Why Choose the ABB PHDT5312 Tmax T5 Horizontal Installation Kit?
The ABB PHDT5312, manufacturer order code 1STQ008459A0000, is a dedicated horizontal installation kit for a 3-pole ABB Tmax T5 withdrawable, motor-operated circuit breaker rated at 400 A. Designed for the ABB System pro E Power modular switchboard range, this accessory supports the mechanical integration of compatible moulded case circuit breaker assemblies into low-voltage electrical distribution systems.
Specified for 800 mm wide switchboard structures, the PHDT5312 provides a purpose-designed horizontal installation arrangement for the ABB Tmax T5 circuit breaker series. Its configuration is intended for a withdrawable breaker equipped with a compatible motor operating mechanism, supporting switchboard layouts that require the specified mounting and operating arrangement.
The ABB PHDT5312 is a circuit breaker installation kit, rather than a complete protective device. It is intended for use with the appropriate 400 A Tmax T5 3-pole withdrawable circuit breaker, compatible motor operating equipment and associated System pro E Power components selected for the finished electrical assembly.

Horizontal Installation for Withdrawable Motor-Operated Tmax T5 Circuit Breakers
The ABB PHDT5312 provides a dedicated installation arrangement for a 3-pole, 400 A Tmax T5 withdrawable circuit breaker with motor operation. Withdrawable circuit breaker configurations are used in electrical distribution assemblies where the breaker can be removed from its associated fixed installation arrangement using the appropriate manufacturer-designed withdrawal system.
A compatible motor operating mechanism allows electrically initiated switching operations when connected to the appropriate control equipment. The PHDT5312 supports the specified mechanical installation but does not independently provide motor operation, electrical protection or a complete withdrawal mechanism.
Within the System pro E Power modular switchboard platform, the PHDT5312 is intended for horizontal installation in an 800 mm wide structure. Correct assembly requires verification of the selected Tmax T5 breaker, withdrawable arrangement, motor operator, electrical connections, mechanical clearances and associated mounting components against the applicable ABB installation instructions.
