Why Choose the ABB XT2H 125 MCP Iu=125 3p F F UL/CSA Motor Circuit Protector?
The ABB XT2H 125 MCP Iu=125 3p F F UL/CSA, order code 1SDA074890R1, 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 an ABB MCP magnetic release with a rated current of 125 A. Its instantaneous magnetic protection is adjustable from 625–1250 A, enabling the protection threshold to be coordinated with motor starting characteristics while providing rapid interruption when a short-circuit fault occurs.
The breaker features a three-pole fixed configuration with front terminals and is rated for systems up to 600 V AC. The XT2H frame provides an H-class 65 kA short-circuit interruption rating, making this UL/CSA configuration suitable for motor control centres, industrial machinery and OEM electrical assemblies requiring robust fault protection.
