Phoenix Contact TMC7 and TMC8 Thermal-Magnetic Overcurrent Protection
Phoenix Contact TMC7 and TMC8 Series Thermal-Magnetic Overcurrent Protectors feature 1-pole, 2-pole, and 3-pole thermal-magnetic Miniature Circuit Breakers (MCBs) available in industry standard B, C, and D-trip curves for DIN rail-mounted applications. These thermal-magnetic overcurrent protectors come with toggle actuation and a visual status indication for overcurrent protection of circuits and loads. The TMC7 and TMC8 series overcurrent protectors operate within the temperature of -35°C to +70°C with a nominal current range of up to 63A. Phoenix Contact TMC7 and TMC8 series circuit breakers with a mechanical life of 20000 cycles are suitable for the protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, and peripheral equipment.
