1SDA054586R1 ABB T5V 400 4-Pole Fixed Breaking Part

Why Choose the ABB 1SDA054586R1 T5V 400 Breaking Part?

The ABB 1SDA054586R1 is a high-performance Tmax T5V 400 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 T5V 400 circuit breaker.

As part of the ABB SACE Tmax T5 series, the T5V 400 platform is engineered for demanding industrial and commercial electrical distribution systems where very high short-circuit interruption performance is required. The breaking part provides the core switching mechanism and can be used with compatible ABB Tmax protection components according to the requirements of the completed circuit breaker assembly.

The T5V 400 platform has a rated uninterrupted current of 400 A, a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 200 kA at 400–415 V AC. Its fixed four-pole construction and front connection arrangement make the 1SDA054586R1 particularly suitable for switchboards, distribution panels and OEM electrical assemblies requiring exceptionally high fault-current interruption capability.
