The thermal-magnetic circuit breakers of the TMC 7 and TMC 8 families reliably protect your applications in the event of an overcurrent or short circuit.
The reliable switching behavior, uninfluenceable positive trip-free mechanism, and color status indicator ensure safety during operation and maintenance. The integrated snap-action mechanism effectively reduces wear on the internal contacts, which increases the service life of the devices.
Three different tripping characteristics and a wide selection of nominal currents up to 63 A in 1-, 2-, and 3-pos. switch versions create a product range that provides perfectly coordinated protection. Optional accessories, such as shunt releases, signal contacts and auxiliary contacts, make it easier to control and evaluate remotely.
TMC 7 miniature circuit breaker
TMC 7 miniature circuit breakers are UL1077-approved and therefore suitable for use as supplementary protection. Full compliance with IEC 60947-2 and the housing design in accordance with DIN 43880 also expand the range of application.
Use the miniature circuit breakers in systems up to 277/480 V AC or 80/125 V DC. The maximum short-circuit current is 7.5 kA.
TMC 8 miniature circuit breaker
TMC 8 miniature circuit breakers are approved in accordance with UL489. Due to their high switching capacity of 10 kA, they are suitable for use as branch circuit protection. Full compliance with IEC 60947-2 and the housing design in accordance with DIN 43880 also expand the range of application.
Use the miniature circuit breakers in systems up to 277/480 V AC or 60/125 V DC. The maximum short-circuit current is 10 kA.
