Products Details

Product Description

CJBF-40 series miniature circuit breaker is a new type product researched and developed by our company depend ently on the basis of absorbing overseas advanced technologies. It complies with the standards GB16917.1 and IEC61009-1.The products are featured with small volume, high breaking apacity of 10KA,neutral breaking function, etc, are widely applied to low-voltage electric systems of AC50 HZ, rated voltage of 230V and rated current not exceed 63A,protect the human body against electric hock,and protect the building and similar purposed circuit equipment against over-current or short circuit.The products also can be used to prevent fire danger caused by earthing fault current due to the damage of insulation of circuits and electrical equipment.The product also has wide current range, up to 63A is available, instead of two pole and medley pole products,saves space.

Machinery Parameter

  • High break capacity 10kA
  • Compact configuration, small size(2 standard dimensions)
  • Centrtc line off capacity, more safe and reliable
  • Duaf function connection terminal, Well connected
  • Contacts condition indicator easy to identify contact information
  • Up to 63A is available, wider current range
  • Matchable with many kinds of accessories, can be equipped with overvoltage protection

Notice Matters

The circuit breaker  should be wired according to the polarity marks, the positiveand negative polarities of power supply should be absolutely proper. Power incoming terminal of circuit breaker is “1” (1P) or “1,3” (2P), loadterminal is “2” (1P) or   “2” (positive  end  of  load),4 ( negative end of load)(2P), don't make wrong connnection.

Order Guidelines

When placing an order, please give clear indications on model, rated current value, tripping type, pole number and quantity of circuit breaker e.g: DAB7-63/DC miniature direct current  circuit  breaker,rated current is 63A tripping type is C, two-pole, C type 40A, 100 pieces, then it can be expressed as: CJBF-63/DC/2-C40100pcs.
