Why Choose the ABB XT1H 160 TMD 40-450 3p F F Circuit Breaker?
The ABB 1SDA080839R1 is a high-performance three-pole moulded case circuit breaker (MCCB) designed for reliable protection of low-voltage electrical distribution systems. Part of the ABB SACE Tmax XT series, this XT1H breaker combines compact construction with a thermomagnetic TMD trip unit to provide dependable overload and short-circuit protection in industrial and commercial installations.
The circuit breaker has a rated current of 40 A and features an adjustable thermal protection range of 28–40 A. Its magnetic instantaneous short-circuit protection is set at 450 A, providing rapid interruption of high fault currents while the thermal element protects cables and connected equipment against sustained overload conditions.
The XT1H 160 is a fixed, three-pole breaker with front terminals and supports operational voltages up to 690 V AC and 500 V DC. The H breaking-capacity version provides an ultimate short-circuit breaking capacity of 70 kA at 415 V AC, making it suitable for demanding distribution systems with substantial prospective fault currents.
