Fixed Tmax XT5 Circuit Breaker Integration for Low-Voltage Switchboards
The ABB 1STQ007618B0000 installation kit is designed to support the mechanical integration of compatible Tmax XT5 3-pole and 4-pole fixed circuit breakers within the System Pro E Power switchboard platform. Its horizontal mounting configuration provides a dedicated installation arrangement for electrical distribution systems using fixed MCCB equipment.
A fixed circuit breaker is installed as part of the switchboard assembly rather than using a plug-in or withdrawable connection arrangement. This configuration is commonly selected for electrical distribution installations where the circuit breaker remains mechanically secured in its designated position and electrical connections are made according to the applicable manufacturer's installation instructions.
The kit is identified for 400 A and 630 A Tmax XT5 circuit breaker configurations. These values describe the compatible circuit breaker arrangements and should not be interpreted as independent current-carrying ratings of the installation kit itself. The actual electrical characteristics of the completed installation depend on the selected circuit breaker, trip unit, conductors, connections and overall switchboard design.
The horizontal installation orientation is an important selection characteristic. The 1STQ007618B0000 should be chosen for the designated horizontal arrangement rather than assumed to support vertical mounting. Similarly, the specified 400 mm width identifies the nominal switchboard configuration for which the kit is intended; it does not establish the physical width of the kit or guarantee compatibility with every enclosure of that nominal width.
Compatibility with both 3-pole and 4-pole Tmax XT5 circuit breakers provides flexibility when designing distribution assemblies with different pole requirements. However, the exact breaker variant, connection arrangement and associated accessories must be checked against the applicable ABB System Pro E Power assembly documentation before installation.
The ABB 1STQ007618B0000 is a mechanical installation kit, not a complete circuit breaker. The Tmax XT5 breaker, trip unit, electrical connections and any additional required components must be selected for the intended application. The supplied kit contents should be verified against the manufacturer's documentation, as the product designation does not independently confirm the inclusion of a circuit breaker or its electrical accessories.
For professional switchboard manufacturers, this dedicated ABB installation accessory helps maintain coordinated mechanical positioning within compatible modular assemblies. Correct installation should follow the relevant ABB instructions and applicable low-voltage switchboard requirements, including the verification of clearances, connections, thermal performance and mechanical support.
