Product Description

The CJBF-63 6kA 10kA electronic residual current circuit breaker is designed by CEJIA engineers for stable operation, precise protection, short opening time, and a high breaking capacity index, all in one small device. The circuit breakers are also produced according to GB 10963 and IEC60898 standards.

The circuit breakers are commonly installed for the overload protection of contactors, relays, and other electrical equipment.

Main functions: short circuit protection, overload protection and isolation.

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: CJBL-63/DC /2-C40100pcs.
