Why Choose the ABB 1SDA054575R1 T4L 320 Breaking Part?
The ABB 1SDA054575R1 is a Tmax T4L 320 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 T4L 320 circuit breaker.
As part of the ABB SACE Tmax T4 series, the T4L 320 platform is designed for demanding industrial and commercial electrical distribution systems requiring high short-circuit interruption performance. The breaking part can be combined with a compatible ABB Tmax protection release selected according to the overload and short-circuit protection requirements of the installation.
The T4L 320 platform has a rated uninterrupted current of 320 A and an ultimate short-circuit breaking capacity of 120 kA at 415 V AC. The fixed four-pole construction and front-terminal arrangement make the 1SDA054575R1 well suited to switchboards, distribution panels and OEM electrical assemblies requiring high-performance circuit interruption.
