Why Choose the ABB XT2H 125 MCP Iu=100 3p F F UL/CSA Motor Circuit Protector?
The ABB XT2H 125 MCP Iu=100 3p F F UL/CSA, order code 1SDA074889R1, is a high-performance three-pole motor circuit protector (MCP) designed for short-circuit protection of low-voltage motor circuits. As part of the ABB SACE Tmax XT / T-Max XT 250 Range, it combines the compact XT2 frame with H-class interruption performance for demanding industrial motor-control applications.
This XT2H motor circuit protector incorporates a magnetic MCP release rated at 100 A. Its instantaneous magnetic protection is adjustable from 300–1100 A, allowing the trip threshold to be coordinated with motor starting currents while providing rapid disconnection during short-circuit conditions.
The breaker features a three-pole fixed configuration with front terminals and is suitable for systems up to 600 V AC. The XT2H frame provides an H-class interruption rating of 65 kA at 480 V AC, making this UL/CSA configuration well suited to motor control centres, industrial machinery and OEM electrical assemblies.
