Audited Supplier CJM9-63 Type miniature circuit breaker(MCB)is mainly used for protection against overload and the short circuit under the AC 50Hz/60Hz, rated voltage 230V/400V, and rated current from 1A to 63A. It also can be used for non-frequent on-and-off switch operations under normal circumstances.
Construction and Feature
·Protection against both overload and short circuit
·High short-circuit capacity
·Easy mounting onto 35mm DIN rail
·Terminal electric devices shall be mounted on Din rail of TH35-7.5D type.
·High short-short capacity 6KA.
·Designed to protect circuit carrying big current up to 63A.
·Contact position indication.
·Used as main switch in household and similar installation.
Normal Service Condition
·Altitude above sea level less than 2000m;
·Ambient temperature -5~+40, average temperature not exceeding +35 within 24 hours;
·Relative Humidity not exceeding 50% at maximum temperature +40 higher relative humidity allowed at lower temperature. For example, relative humidity 90% allowed at +20;
·Pollution class: II (means generally only non-electricity conducting pollution is considered, and also considers temporary electricity conducting pollution occasionally caused by condensed dew);
·Perpendicular installation with allowed tolerance 5.
