Molded Case Circuit Breakers

Molded Case Circuit Breakers (MCCB) are low-voltage protection devices that have a wide range of applications in residential, commercial, and industrial sectors. They are used to protect a circuit from over current and short circuit conditions. Depending on the application, they are available in a variety of sizes and ratings. MCCBs are, generally, rated for currents up to 1000 amperes. They are known to be particularly reliable and long lasting when maintained properly.

MCCBs contain a number of moving parts that are working in close coordination. They require periodic inspection and maintenance to ensure that they operate reliably when required. Contact timings, contact bounce, non-simultaneity of contacts, current and voltage characteristics, static contact resistance, insulation tests, endurance tests, etc. are some of the tests performed on MCCBs.

Crest manufactures a full range of MCCB testing products for OEMs for ensuring the quality of the product before delivery and for end users to ensure optimum performance of their assets.
