2P 25A Circuit Breaker MCB
TOMC3-63 AC 2P 25A Circuit Breaker MCB from TONGOU is used in lighting distribution systems or motor distribution systems for protecting overload and short circuits in the system.
The product is neoteric in structure, light in weight, reliable, and excellent in performance. Its frame and parts adopt plastics of high fire resistance and shockproof.
The product, with long life, is mainly used in AC 50Hz/60Hz single-pole 240V or two, three, four poles up to 415V circuit for overload and short circuit protection, as well as for unfrequently switching electric equipment and lighting circuit in normal case.
2P 25A Circuit Breaker Special Tips
1. MCB is for non-professional operation by those untrained, and no maintenance is required.
2. B, C, D tripping curve.
3. It is recommended to install special devices, such as surge protection devices, lightning arresters, etc., on the upstream line of the MCB to prevent potential surge voltage and current from appearing on the power input side.
4. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of fault, and thus provides protection against electric shock.
