Reliable quality and good credit standing are our principles, which will help us at a top-ranking position. Adhering to the tenet of “quality first, customer supreme” for China Miniature Circuit Breaker and Low-Voltage, now we have 8 years experience of production and 5 years experience in trading with the customers all over the world. our clients mainly distributed in the North America, Africa and Eastern Europe. we can supply high quality items with the very competitive price.
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.
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.
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.
