Blue Jay DZ47 Miniature Circuit Breaker

Blue Jay DZ47 Miniature Circuit Breaker is an AC MCB circuit breaker series. It is used in lighting distribution systems or motor distribution systems for protecting against overload and short-circuit conditions. The electrical miniature circuit breaker is light in weight reliable and excellent in performance.

This electronic miniature circuit breaker has a high breaking capacity of up to 6kA. Its case and items are adopted with highly fire-resistant and shockproof plastics. The DZ47 Miniature Circuit Breaker has mainly used in AC 50/60Hz single-pole 230V or two three four-pole 400V circuits for overload and short circuit protection as well as for on-off switching electric equipment and lighting circuit. The product complies with EN/IEC60898.

  • Air Circulation,When two poles are placed adjacent to each other, the channels between two poles form a tunnel resulting in very effective air circulation around individual poles.
  • DIN Rail Mountable for easy mounting/ demounting inside DB.
  • Dual connect terminal at incoming side – Two types of busbars can be used, that is, Fork Type and Pin Type.
  • The terminals are suitable for cables up to 25 mm 2 cross section area thus making it suitable for copper and aluminum cables.
  • OFF position for personal safety during maintenance
  • ON position for extremely critical load
  • Trip free mechanism – MCB trips even if held in ON position.
  • Low efficient watt loss, thus energy.
