Recognized motor circuit protectors require an evaluated combination motor-controller assembly and separate motor overload protection. Do not use an MCP as a general-purpose thermal-magnetic branch breaker. The catalogue repeats M1MN30T3L in the H column; an unproven M1MH30T3L code is therefore not offered.
Typical applications
- Short-circuit protection in evaluated combination motor controllers.
- Industrial motor circuits using a coordinated contactor, separate overload relay and correctly adjusted magnetic trip unit.
