Why Choose the ABB 1STQ008424A0000 PHBT4402 T4 Circuit Breaker Installation Kit?
The ABB 1STQ008424A0000, also identified as PHBT4402, is a dedicated horizontal circuit breaker installation kit for the ABB System Pro E Power low-voltage switchboard range. It is designed for the installation of two compatible ABB Tmax T4 fixed moulded case circuit breakers within a modular electrical distribution assembly.
The ABB PHBT4402 supports compatible 3-pole and 4-pole Tmax T4 fixed circuit breaker configurations. Its application-specific mechanical mounting arrangement helps electrical panel builders position two breakers horizontally within a coordinated System Pro E Power switchboard section.
Specified for a nominal 400 mm wide switchboard section, the kit carries the manufacturer designation 2 T4 KIT 3-4P FIXED I HORIZ. W=400MM. It provides a practical mounting solution for industrial and commercial electrical distribution projects requiring fixed circuit breaker installation rather than plug-in or withdrawable execution.

Horizontal Fixed Tmax T4 Installation for Modular Power Distribution
The ABB PHBT4402 installation kit provides a mechanical mounting arrangement for two compatible Tmax T4 fixed moulded case circuit breakers within a System Pro E Power switchboard. Fixed circuit breakers are installed as part of the electrical assembly using their designated mounting and connection arrangements, rather than the plug-in bases associated with plug-in executions.
The kit's horizontal layout supports the integration of two compatible breakers into a nominal 400 mm wide switchboard section. Circuit protection characteristics, rated current and switching performance depend on the separately selected Tmax T4 breakers and their trip units. The PHBT4402 itself is a mechanical installation accessory and does not independently provide electrical protection or switching functionality.
Typical Applications
- ABB System Pro E Power low-voltage switchboard construction.
- Installation of two compatible ABB Tmax T4 fixed circuit breakers.
- Industrial main and sub-distribution boards.
- Commercial building electrical distribution systems.
- Manufacturing and production facility power distribution.
- OEM electrical panel building and switchboard manufacturing.
- Modular distribution assemblies requiring horizontal fixed breaker installation.
- Compatible switchboard refurbishment and circuit breaker mounting upgrades.

Frequently Asked Questions
What is the ABB 1STQ008424A0000 PHBT4402 used for?
The ABB PHBT4402 is a horizontal installation kit designed to accommodate two compatible ABB Tmax T4 fixed moulded case circuit breakers within System Pro E Power low-voltage switchboard assemblies.
Which circuit breakers are compatible with the ABB PHBT4402?
The kit is specified for compatible ABB Tmax T4 fixed circuit breakers in 3-pole and 4-pole configurations. The exact breaker versions and associated mounting accessories must match the relevant ABB installation requirements.
How many circuit breakers can the PHBT4402 installation kit accommodate?
The product designation identifies an installation arrangement for two ABB Tmax T4 circuit breakers in the specified horizontal fixed-mounted configuration.
What switchboard width is required for the ABB PHBT4402?
The PHBT4402 is specified for a nominal 400 mm wide switchboard section within the ABB System Pro E Power range. This is the nominal switchboard configuration width, not a confirmed overall physical dimension of the kit.
Does the ABB 1STQ008424A0000 include the Tmax T4 circuit breakers?
The ABB 1STQ008424A0000 is a mechanical installation kit rather than a complete circuit breaker assembly. The compatible Tmax T4 fixed circuit breakers and any additional required electrical or mounting accessories must be selected according to the complete switchboard design.
