Why Choose the ABB 1SDA054755R1 T5 400 W FP 3p EF Fixed Part?
The ABB 1SDA054755R1 is a three-pole fixed part for a withdrawable ABB Tmax T5 400 moulded-case circuit breaker. Part of the ABB Tmax T4–T8 circuit-breaker range, this fixed-part assembly provides the stationary mounting and electrical connection interface required for a compatible withdrawable T5 400 circuit breaker.
In a withdrawable installation, the fixed part remains installed within the switchboard while the compatible moving part and circuit breaker can be withdrawn for inspection, servicing or replacement. This configuration supports maintainable low-voltage distribution systems by allowing breaker access without removing the permanently installed fixed-part assembly and its associated connections.
The 1SDA054755R1 features a three-pole configuration with extended front (EF) terminals. Designed specifically for the ABB Tmax T5 400 platform, it is suitable for industrial switchboards and distribution assemblies requiring a withdrawable circuit-breaker arrangement.
