1STQ007123B0000 ABB Dual XT5 Withdrawable Kit 3/4-Pole 400 A Horizontal W600

Why Choose the ABB 1STQ007123B0000 Dual XT5 Withdrawable Circuit Breaker Installation Kit?

The ABB 1STQ007123B0000 is a specialised dual XT5 withdrawable circuit-breaker installation kit designed for compatible ABB Tmax XT5 moulded case circuit breakers within the ABB System Pro E Power modular switchboard system. This accessory is intended for low-voltage electrical distribution assemblies requiring a coordinated installation arrangement for two compatible XT5 circuit breakers.

Identified by ABB as 2 XT5 KIT 3-4P WITH.IM 400A HORIZ.W=600, the kit is specified for a two-breaker XT5 arrangement, supporting compatible three-pole or four-pole withdrawable configurations in the 400 A current class. Its horizontal mounting designation and 600 mm nominal switchboard width make it suitable for the corresponding System Pro E Power compartment configuration.

Designed for professional switchboard manufacturers, electrical engineers and panel builders, the ABB 1STQ007123B0000 supports organised circuit-breaker integration in industrial and commercial electrical distribution systems. Its dedicated installation configuration helps engineers select the appropriate ABB accessory for a dual-breaker arrangement while maintaining compatibility with the intended modular switchboard structure.

Engineered for Dual XT5 Withdrawable Circuit-Breaker Integration

The ABB Tmax XT5 circuit-breaker family is used in low-voltage electrical distribution systems requiring circuit protection and switching functionality. Within compatible switchboard assemblies, withdrawable circuit-breaker configurations provide a dedicated arrangement for connecting and withdrawing equipment according to the applicable operating and maintenance procedures.

The ABB 1STQ007123B0000 is specifically identified as a kit for two XT5 circuit breakers, with three-pole or four-pole compatibility, a withdrawable installation designation and horizontal mounting. This combination distinguishes it from single-breaker installation kits and fixed or plug-in arrangements within the wider ABB accessory range.

The specified 600 mm nominal width is an important selection parameter for panel builders configuring System Pro E Power switchboard compartments. Matching the correct installation kit to the intended enclosure structure helps ensure that the mechanical arrangement is planned around the appropriate equipment configuration.

The 400 A designation identifies the current class associated with this installation kit; it does not independently establish the continuous current rating of the finished switchboard or confirm the rating of every compatible circuit breaker. Final current-carrying capability depends on the selected breakers, electrical connections, installation conditions and verified assembly design.

The WITH.IM wording is retained as ABB's stated configuration designation. The precise interpretation of the IM suffix, the supplied mechanical components and the compatibility of particular withdrawal or operating accessories should be established using the relevant ABB installation documentation.

This product is an installation kit rather than a complete circuit-breaker assembly. It should not be assumed to include two circuit breakers, protective trip units, motor operators or all electrical connection components unless those items are expressly confirmed in the manufacturer's bill of materials.
