The Schneider Electric C166TM160 is a trip unit designed for the ComPacT NSX160 molded case circuit breaker series. This specific unit, the TM160D, is engineered to provide thermal magnetic protection for electrical circuits. It is configured for a 4-pole breaker with 3D protection, meaning the neutral pole is not protected by the trip unit itself, a common configuration in systems where neutral current is not a primary concern for overcurrent protection.

Applications & compatibility

This trip unit is integral to the operation of ComPacT NSX160 circuit breakers, commonly found in industrial power distribution panels, motor control centers, and machinery requiring reliable overcurrent protection. Its 4-pole configuration makes it suitable for systems with a neutral conductor that does not require individual overcurrent tripping.
