Why Choose the ABB XT5S 400 TMA 400-4000 3P Circuit Breaker?
The ABB XT5S 400 TMA 400-4000 3P F F 1SDA100415R1 is a fixed three-pole SACE Tmax XT5 moulded case circuit breaker designed for reliable protection of low-voltage electrical distribution systems. Rated at 400 A, it combines the XT5S breaking part with a TMA thermomagnetic release for overload and short-circuit protection.
The TMA thermomagnetic trip unit provides thermal overload protection together with adjustable instantaneous magnetic short-circuit protection. Its instantaneous magnetic threshold is adjustable from 2000–4000 A, enabling the breaker to be coordinated with the characteristics and fault-protection requirements of the connected circuit.
The 1SDA100415R1 is supplied as a fixed three-pole breaker with front terminals. The XT5S performance class provides an ultimate short-circuit breaking capacity of 50 kA at 415 V AC, making it suitable for demanding industrial, commercial and infrastructure installations requiring robust fault interruption.
