Sell TAIXI MCB DZ47 220V 380V Mini Miniature Circuit Breaker 1P 2P 6A 16A 32A 40A 50A 63A 80A 100A 125A Air Switch Protection best price

DZ47-63 miniature circuit breaker (DZ47 air switch) is mainly suitable for AC 50/60Hz rated working voltage of 230V/400V and below, rated current to 63A circuit, the new circuit breaker is mainly used for electrical circuits and modern buildings The overload and short circuit protection of the equipment is also suitable for infrequent operation and isolation of the circuit. Structural features DZ47-63 miniature circuit breaker is composed of plastic shell, initial operation structure, contact solitary elimination system, clever buckle mechanism, etc. The shell is made of high-flame retardant, high-strength special plastics. Strong impact resistance and light weight The parts of the circuit breaker operating mechanism are made of high-strength plastic products, which ensure the sensitivity and reliability while obtaining the lowest rotational intrusion, so that the time from the start of the short-circuit fault to the action of the tripping mechanism is very short. The tripping mechanism is composed of two parts: a bimetallic overload inverse time tripping mechanism and a short-loose instantaneous electromagnetic mechanism. The contact arc extinguishing system uses a special arc guide angle and aisle extinguishing chamber, and has significant current limiting characteristics. It is mainly used for overload and short circuit protection of lighting, power distribution lines and equipment in office buildings, residences and similar buildings. It can also be used for infrequent line conversion under normal conditions. Main specifications of DZ47-63 miniature circuit breaker (DZ47 air switch): According to the rated current ln points: 1A, 3A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A. According to the number of poles (POLE): 1P. Single pole; 2P. Two poles; 3P. Three poles; 4P. Four poles. According to the form of the instantaneous release of the circuit breaker: .C type (5In~10Iln); Machine-pumped electrical life: the circuit breaker is switched on and off the rated current under the specified bottle voltage, the power factor is 0.5-0.9, and the operation cycle is 120 times (>32A) or 240 times (324) per hour. , Its electrical life is 4000 times, and its mechanical life is 10000 times.
