New DZ47 CJM9-63 3P C63 6kA AC Household Electricity MCB Miniature Circuit Breaker

CJM8-63 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.

Products Details

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.
