Description
25A Breaker Curve C MCB
It offers a compact solution for protection requirements. The S200 devices are UL tested current limiting and DIN rail mounted.
The S200 is available with application-specific trip characteristics to provide maximum circuit protection. The breakers offer thermal-magnetic trip protection according to B, C, D, K, and Z characteristics.
For the worldwide market, the breakers carry UL, CSA, IEC, CE, and many other agency approvals and certifications. Miniature circuit breakers ensure electrical safety in multiple applications.
They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.
25A Breaker Feature
1. MCB is for non-professional operation by those untrained, and no maintenance is required
2. Particular devices such as surge protective devices, surge arresters, etc are recommended to install at the upstream line to MCB as a precaution against potential surge voltage and current occurring at its power input side.
3. 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.
