Why Choose the ABB XT1H 160 TMD 32-450 4p F F Circuit Breaker?
The ABB 1SDA080853R1 is a high-performance four-pole moulded case circuit breaker (MCCB) designed for dependable protection of low-voltage electrical distribution systems against overload and short-circuit faults. Part of the ABB SACE Tmax XT series, this XT1H 160 breaker combines compact construction with a TMD thermomagnetic trip unit for reliable circuit protection in industrial and commercial installations.
The circuit breaker has a rated current of 32 A and an adjustable thermal overload protection range of 22.4–32 A. Its instantaneous magnetic short-circuit protection is set at 450 A, providing rapid interruption of severe fault currents while the thermal element protects cables and connected equipment against sustained overload conditions.
With a four-pole fixed configuration, front terminals and a rated operational voltage of up to 690 V AC, the XT1H 160 is suitable for demanding low-voltage distribution applications. The H breaking-capacity version provides an ultimate short-circuit breaking capacity of 70 kA at 400–415 V AC, making the 1SDA080853R1 suitable for switchboards and electrical systems with substantial prospective fault currents.
