Product models: CJ20-250A-F16X12x1.5, CJ20-250A-R15X12x1.5, CJ20-400A-F19.25x13.5x1.5, CJ20-400A-R19.2x13.7x1.5, CJ20-630A-F26.5x17.2x1.5 Product Price: 300 yuan - 800 yuan the company's product quality has a very high hardness and patience grinding low friction as well as special parts of ultra precision mirror surface and interface CJ20 ac contactor contact nod performance: the conductive ability by the measurement of 58-60 degrees or so by measuring temperature of 60 degrees or so, mechanical life of up to 100 times or so, the electrical life of up to 10 times or so CM1 molded case circuit breaker contact nod performance, conductive ability by 60 degrees or so, temperature can reach 62 degrees, mechanical life of up to 8000 times or so, The electrical life can reach 1500 times C45, C65, L7. The performance of F360 can reach 40 degrees by temperature rise measurement, the mechanical life can reach 16,000 times, and the electrical life can reach 4000 times. However, it depends on the indoor and outdoor temperature and environment. Performance life have different copper contact nod, bp (nod) composite horn touch touch resistance stability good oxidation resistance temperature reached national nod standard long-term use of temperature rise will not change block ability good fusion welding resistance never happen contact welding phenomenon is widely used in ac contactor circuit breaker, air switch, leakage protector, leakage switch yueqing Long Qiang alloy co., LTD
