Miniature Circuit Breaker

A whole new generation of Shanghai Schneider JC65N / C series of small devices ???? JC65 high segmentation mini circuit breaker for AC 50HZ or 60HZ, rated working voltage of 230 / 400V, rated current of 63A the following line, and used to office buildings, residential buildings and similar lighting, power distribution lines and electrical equipment overload, short circuit protection, under normal circumstances can be as infrequent line conversion purposes, the product has advanced structure, reliable performance, points segment high capacity, compact and beautiful appearance and other characteristics. Shell and shock-resistant parts, made of high fire-retardant materials. ?? Select breaker (air switch) ampere calculation a = 735W≈750W1.5 match = 1.5 × 750W = 1125W2 match = 2 × 750W = 1500W2.5 match = 2.5 × 750W = 1875? W This calculation method in order and so on. Three air conditioning? A number of air should switch to select? (220V voltage) 750W × 3 匹 = 2250W × 3 times (inrush currents) = 6750W ÷ 220V = 30.68A≈32A. Example 5 A number of air conditioning switch should choose? (? 380V voltage) 750W × 5 匹 = 3750W × 3 times (inrush currents) = 1125W ÷ 380V = 29.60≈32A (power ÷ voltage = amps) circuit breakers (air switch) polarity and representation unipolar (1P) :? 220V bipolar cut FireWire (2P): 230V / 415V FireWire and the zero line and cut off three (3P):? 230V / 415V three-phase lines are all cut off * (4P):? 230V / 415V three-phase firing a phase? All off the zero line. Difference breaker breaker with DPN 1P: ???? 1P into the breaker is FireWire, zero line does not feed, DPN is the hot and neutral lines simultaneously breaker, when the hot and neutral lines cut off at the same time, residents of the user said higher security. ???? 2P breaker for double inlet, namely hot and neutral lines into the breaker, but the width is wider than the 1P 2P circuit breakers and circuit breakers DPN doubled. ???? Leakage protection: actually refers to a circuit breaker with leakage protection device, when the leakage current role is more than 30 mA, leakage attachments automatically wind up, to protect human safety. ?? Model and its implications JC65N / C-63 ** JC- corporate code N- MCCB (including small) number 63- circuit breakers designed C- frame degree rated current ** - code segment capacity and number of poles Series complete structural features: the ability to be divided into segments according to 6KA, 10KA has cost optimization, adapted to different places. Wiring: using multi-function terminals, which can take a round copper conductors and busbars. Isolation: Isolated comply GB14048.2 standard safety requirements, impulse withstand voltage 6KV, handle the contact position, the open position can be locked attachment function: can be assembled shunt, undervoltage, auxiliary contacts, alarm contacts, etc. Accessories Accessories: 1, MX + OF shunt trip attachment 2, OF auxiliary contact Annex 3, SD alarm contacts Accessories
