Why Choose the ABB XT1S 160 TMD 32-450 4P Circuit Breaker?
The ABB XT1S 160 TMD 32-450 4P, order code 1SDA080848R1, is a compact moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range, designed to provide dependable overload and short-circuit protection in low-voltage electrical distribution systems. This configuration combines the XT1S 160 frame with a TMD thermomagnetic release and four-pole construction for industrial and commercial power-distribution applications.
The circuit breaker has a rated current of 32 A, with adjustable thermal overload protection from approximately 22.4–32 A and a fixed 450 A magnetic trip level. Its TMD release therefore provides thermal protection against sustained overloads together with rapid magnetic operation under short-circuit conditions.
The 1SDA080848R1 is supplied as a four-pole fixed circuit breaker with front terminals. Its XT1S short-circuit performance level provides an ultimate breaking capacity of 50 kA at 415 V AC, while the breaker is rated for operation up to 690 V AC, making it a versatile solution for compact low-voltage switchboards and distribution assemblies.
