Motor protection
The overload and short-circuit releases are designed for optimal
protection and direct starting of three-phase AC squirrel-cage motors.
The molded case circuit breakers for motor protection have phase-
failure sensitivity and a thermal image that protects the motor against
overheating. The adjustable time lag class enables users to adjust the
overload release to the startup conditions of the motor to be protected.
