ZPM1-63 AC 6kA Miniature Circuit Breaker
ZPM1-63 AC miniature circuit breaker for overload and short circuit protection, with rated current from 1A to 63A, rated voltage 240/415V, 6kA breaking capacity, and B, C, D tripping curves.
Product Overview
Zivopower ZPM1-63 AC Miniature Circuit Breaker is designed for reliable overload and short circuit protection in residential, commercial, and light industrial electrical distribution systems. The ZPM1-63 offers stable protection performance with thermo-magnetic trip operation and a rated current range from 1A to 63A.
The product is designed with a long service life thanks to its energy-storage operating mechanism, while the enclosure and functional parts are made from high-quality plastics with flame-retardant, heat-resistant, and impulse-proof properties. It also provides higher current-limiting capacity, making it a cost-effective MCB solution.
With pole options including 1P, 1P+N, 2P, 3P, 3P+N, and 4P, plus B, C, and D tripping curves, this breaker is suitable for a wide range of circuit protection requirements. The product is designed for mounting on a 35mm DIN rail and supports connection from both top and bottom.
