Why Choose the ABB T4V320 Breaking Part 3p FF?
The ABB T4V320 Breaking Part 3p FF, order code 1SDA054571R1, is a high-performance three-pole breaking unit from the ABB SACE Tmax T moulded case circuit breaker range. Designed around the T4V 320 frame, it provides the main switching and current-carrying section for compatible Tmax T4 circuit breaker configurations.
This breaking part has a rated uninterrupted current of 320 A at 40 °C and uses ABB's high-performance V breaking-capacity class. It is supplied in a fixed three-pole configuration with front terminals, making it suitable for integration into industrial switchboards, distribution panels and OEM electrical assemblies.
The T4V320 platform provides an ultimate short-circuit breaking capacity of 200 kA at 415 V AC, supporting demanding installations with high prospective fault currents. As a breaking part rather than a complete circuit breaker with a protection release, the 1SDA054571R1 is intended to be combined with a compatible ABB Tmax T4 trip unit and the accessories required by the application.
