Tips: Difference between miniature circuit breaker and molded case circuit breaker
- Miniature circuit breaker
Miniature circuit breaker, short for MCB, is a circuit breaker product with a very large range and quantity. Its main function is to provide protection for building electrical terminal power distribution devices. Because both belong to the circuit breaker, and the molded case circuit breaker is mostly used for small-capacity switching. - Molded case circuit breaker
Molded case circuit breaker is known as MCCB. The main function of this circuit breaker is to provide protection functions for overload and short circuit in the low-voltage power distribution system and motor protection circuit. Because of its reliability and stability, it has become a very widely used product in industry.
16 amp 4 pole thermal-magnetic mini circuit breaker meets IEC standard for 35 mm DIN rail mounting with 6kA interrupt capacity. C curve trip characteristic, is designed for the short circuit and overload protection in the AC 50Hz circuit, 230/400V voltage.
