ABB 1SDA075145R1 XT3S 225 is a fixed four-pole 150 A moulded case circuit breaker with front terminals, a fully rated neutral, a TMF thermal-magnetic release and a 35 kA interruption rating at 480 V AC for UL/CSA applications.

The ABB 1SDA075145R1, designated XT3S 225 TMF 150-1500 4p F F UL/CSA, is a fixed four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Built on the XT3S 225 frame, it has a rated current of 150 A and incorporates a TMF thermal-magnetic release for reliable overload and short-circuit protection.
The TMF release combines thermal overload protection with instantaneous magnetic short-circuit protection. On this configuration, the protection is rated at 150 A with a 1500 A instantaneous magnetic trip threshold, providing straightforward circuit protection without requiring an electronically powered trip unit.
Designed for UL/CSA applications, the 1SDA075145R1 is supplied as a fixed four-pole breaker with front terminals and a fully rated neutral. ABB specifies a rated voltage of 600Y/347 V and an S-class interruption rating of 35 kA at 480 V AC, making it suitable for industrial, commercial and OEM low-voltage distribution systems.
The TMF release combines two established protection principles within the circuit breaker. Its thermal element responds to sustained overload currents that could overheat conductors and connected equipment, while the magnetic element provides rapid tripping when a severe short-circuit current reaches the instantaneous operating threshold.
For the ABB 1SDA075145R1, the TMF release provides a 150 A overload rating and a 1500 A instantaneous magnetic threshold. The four-pole construction incorporates a fully rated neutral, while the XT3S performance level delivers 35 kA at 480 V AC interruption capability for demanding UL/CSA distribution applications.
