Why Choose the ABB 1STQ008461A0000 PHDT5425 T5 Withdrawable Circuit Breaker Installation Kit?
The ABB 1STQ008461A0000, manufacturer type PHDT5425, is a dedicated horizontal installation kit for two ABB Tmax T5 moulded case circuit breakers within the ABB System Pro E Power low-voltage switchboard system. Designed for compatible 3-pole and 4-pole withdrawable circuit breakers, it supports an interlocked installation arrangement with a specified 400 A breaker configuration.
Engineered for a nominal 800 mm wide switchboard section, the PHDT5425 provides a coordinated mechanical installation solution for two compatible Tmax T5 breakers. Its manufacturer designation, 2 T5 KIT 3-4P WITHD. I 400A HOR.W=800MM, identifies the dual-breaker arrangement, withdrawable execution, interlocked configuration, 400 A specification and horizontal mounting orientation.
The ABB PHDT5425 is intended for professional power distribution assemblies requiring two withdrawable Tmax T5 circuit breakers in a coordinated layout. Withdrawable configurations can support maintenance and replacement procedures when used with the correct breaker and connection accessories. The PHDT5425 is a mechanical installation kit rather than a complete circuit breaker or interlocking assembly, so the appropriate breakers, withdrawable components and interlocking equipment must be selected for the finished installation.

Horizontal Interlocked Tmax T5 Installation for Withdrawable Power Distribution
The ABB PHDT5425 is designed for switchboard arrangements requiring two compatible withdrawable Tmax T5 circuit breakers in a horizontal configuration. Withdrawable breaker systems incorporate dedicated connection and withdrawal arrangements, allowing the breaker to be moved between its specified operating positions when the correct equipment is installed. This can support planned inspection, maintenance and equipment replacement procedures in appropriately engineered electrical distribution systems.
The product designation also identifies an interlocked arrangement. Interlocking is used where the operating states of two circuit breakers must be coordinated, such as in certain source-selection or changeover applications. The installation kit does not independently provide the interlocking function or determine the protection characteristics of the completed assembly. The selected breakers, withdrawal mechanisms, interlocking accessories and electrical connections must be verified against the applicable ABB technical documentation.
Understanding the 400 A Withdrawable Breaker Configuration
The 400 A reference in the PHDT5425 designation identifies the breaker configuration for which the installation kit is specified. It should not be interpreted as an independently certified current-carrying rating for the mechanical mounting kit. The actual current rating, trip-unit settings, breaking capacity and electrical performance of the finished installation depend on the specific Tmax T5 circuit breakers and associated components selected.
The specified 800 mm width refers to the compatible System Pro E Power switchboard section rather than the independently confirmed physical width of the kit. Before installation, panel builders should verify the required compartment arrangement, breaker execution, mounting clearances, withdrawal provisions and interlocking components against ABB's relevant assembly instructions.
Typical Applications
- ABB System Pro E Power low-voltage switchboard construction.
- Installation of two compatible ABB Tmax T5 withdrawable circuit breakers.
- Industrial main and sub-distribution switchboards.
- Commercial building electrical distribution assemblies.
- Interlocked dual-breaker arrangements in engineered power distribution systems.
- Source-selection and changeover switchboard layouts, where appropriately designed.
- Electrical installations requiring withdrawable breaker configurations.
- OEM switchboard manufacturing and compatible distribution board refurbishment.

Frequently Asked Questions
What is the ABB 1STQ008461A0000 PHDT5425 used for?
The ABB PHDT5425 is a horizontal installation kit for two compatible ABB Tmax T5 withdrawable moulded case circuit breakers in an interlocked arrangement within System Pro E Power low-voltage switchboards.
Which circuit breakers are compatible with the ABB PHDT5425?
The kit is specified for compatible ABB Tmax T5 3-pole or 4-pole withdrawable circuit breakers in the designated 400 A configuration. Exact breaker versions, withdrawal accessories and installation requirements must be checked against ABB documentation.
What does WITHD. I 400A HOR.W=800MM mean?
WITHD. indicates withdrawable breaker execution, I identifies an interlocked arrangement, 400A specifies the designated breaker current configuration, and HOR.W=800MM identifies horizontal installation in a nominal 800 mm wide switchboard section.
Does the ABB PHDT5425 include the Tmax T5 circuit breakers?
No. The ABB 1STQ008461A0000 is an installation kit rather than a complete circuit breaker assembly. Compatible Tmax T5 breakers and any additional withdrawal, connection or interlocking components must be selected according to the complete switchboard design.
Does the ABB PHDT5425 provide a complete interlocking system?
No. The PHDT5425 is intended for an interlocked installation arrangement, but the required interlocking function depends on correctly selected and installed breaker mechanisms and associated equipment. The complete arrangement must be verified against the applicable ABB instructions.
