Why Choose the ABB 1SDA054564R1 T4H 250 Breaking Part?
The ABB 1SDA054564R1 is a Tmax T4H 250 breaking part designed for use within ABB's modular Tmax moulded case circuit breaker system. This version provides a fixed four-pole breaker body with front terminals, forming the switching and interruption section of a suitably configured T4H 250 circuit breaker.
As part of the ABB SACE Tmax T4 series, the T4H 250 platform is engineered for dependable protection and switching in demanding industrial and commercial electrical distribution systems. The breaking part is supplied without a dedicated trip release, allowing a compatible ABB Tmax protection unit to be selected according to the required protection characteristics.
The T4H 250 frame has a rated uninterrupted current of 250 A at 40 °C and an ultimate short-circuit breaking capacity of 70 kA at 415 V AC. Its fixed four-pole construction and front terminals provide a robust solution for switchboards, distribution panels and OEM electrical assemblies where high fault-breaking performance is required.
