£1,944.33
The ABB T4V250 Breaking Part 3p FF, order code 1SDA054561R1, is a high-performance three-pole breaking unit from the ABB SACE Tmax T moulded case circuit breaker range. Designed around the T4V 250 frame, it provides the main switching and current-carrying section for compatible Tmax T4 circuit breaker configurations.
This breaking part uses the T4V 250 platform and is supplied in a fixed three-pole configuration with front terminals. It has a rated uninterrupted current of 250 A and is designed for operating voltages up to 690 V AC and 750 V DC, providing a robust foundation for demanding industrial circuit protection assemblies.
The V short-circuit performance level delivers an ultimate breaking capacity of 200 kA at 400/415 V AC and 150 kA at 690 V AC. As a breaking part rather than a complete circuit breaker with protection release, it is intended to be combined with compatible ABB Tmax T4 trip units and accessories appropriate to the required application.
The breaking unit forms the main switching and fault-current interruption section of a modular moulded case circuit breaker. The T4V 250 version provides particularly high short-circuit performance, allowing compatible Tmax T4 assemblies to be used in industrial electrical systems with substantial prospective fault currents.
ABB's modular Tmax T architecture allows the breaking part to be combined with an appropriate protection release and compatible accessories. This enables the circuit breaker configuration to be matched to the protection requirements of industrial switchboards, machinery and power distribution installations.
