Why Choose the ABB XT1H 125 TMF 1SDA074702R1 Circuit Breaker?
The ABB XT1H 125 TMF 1SDA074702R1 is a compact three-pole moulded case circuit breaker (MCCB) designed for dependable low-voltage circuit protection in UL/CSA applications. Part of the ABB SACE Tmax XT1 range, it combines a 125 A frame with a 60 A TMF thermomagnetic trip unit for overload and short-circuit protection.
This XT1H circuit breaker is supplied in a fixed configuration with front terminals. Its TMF release has a rated current of 60 A and an instantaneous magnetic short-circuit setting of 600 A, providing straightforward thermal and magnetic protection without the configuration requirements of an electronic trip unit.
The XT1H high-breaking-capacity version provides an H interruption rating of 65 kA at 480 V AC and is rated at 600Y/347 V AC. Its compact three-pole construction, high fault-current capability and UL-certified design make the 1SDA074702R1 suitable for industrial, commercial and OEM electrical distribution equipment.
