ZW28-12F vacuum circuit breaker

 Company Name; Yueqing Wei Chuan Electric Co. at www.wcele.com >> (1) Model ZW8-12GF "Z represents the vacuum load" W represents the outdoor, 12 is representative of voltage, F is representative of intelligent demarcation, G It is with isolation (2) Products; manual operation of the circuit breaker and electric operation, there are voltage transformers, stainless steel steel. (3) 630A-1250A is representative of current, (20KVA-25KVA-31.5KVA is representative of the short-circuit current is interrupted.) (4) telephone customer orders;. 0577-62708571 &&&&&& Granville (5) The Company fax; 0577-62708570. (6) The company delivery time 1-2 days, the goods are starting from Zhejiang Province, (7) household customer orders to note the following, first, how much voltage and current is how much the operation is electric and manual operation voltage 48V-110V-220V (8) If you do not understand, the customer can call the company telephone consultation. 24-hour telephone; 0577-62708571 (9) product if there are problems, the province 48 hours to arrive within 24 hours to reach the maintenance, customers can rest assured that with ZW28 series vacuum circuit breaker combination with isolation circuit breakers, rated voltage 12KV, three-phase 50HZ AC high voltage outdoor switchgear, built-in voltage 12KV into a 220V operating voltage, CT is built-in current transformer, mainly used to breaking closing rural power off load current, City and small power system, overload current, short circuit current. The overall structure of the three-phase common tank type, three-phase vacuum interrupter in a metal box, use SMC insulation and white insulation and ground insulation, reliable performance, high dielectric strength. The product can also be applied to fit with coincident controller easy to take power for the occasion, PT type coincides with the controller with no power applied to the occasion, intelligent circuit breaker for power supply and radiating ring network power supply system, the help system to eliminate transient faults Automatic restoration of electricity, but also a permanent fault isolation, achieve distribution automation. Intelligent Circuit Breaker with 1 to 3 times reclosing function, and can coincide tuning parameters; intelligent circuit breaker with inrush current control, overcurrent and short circuit instantaneous trip protection features three sections of the composite, and the continuous tuning parameters; intelligent circuit breaker with small current grounding protection function and parameters can be continuous tuning; intelligent circuit breaker either wired remote control, wireless remote control can also be in the bar. For AC 50Hz, voltage 10 ~ 12kV three-phase power system as breaking, closing load current purposes, it has overload and short circuit protection, instantaneous trip protection, definite time delay protection, automatic reclosing function, but also according to user needs equipped with surge arresters or isolating switch (ie, a combination of circuit breakers and disconnectors, hereinafter referred to as "a combination of intelligent breaker"), etc. The self-powered intelligent circuit breaker, the nearest remote control, with CT, PT interface to meet the requirements of circuit breaker interrupter device telemetry, so the circuit breaker can operate with a load, not only to operate the load current, also operate fault (short circuit) current; breaker has a good package, it is a simple observation breaker , which is not visually determine in the closed or open position. Isolation switch is not interrupter device, although rules of which can operate in the case of the load current is less than 5A, but it does not belong with the overall load operation; but the simple isolation switch structure could tell from the appearance of its operational state, when overhaul obvious break point. Breaker Acronym in use for the "switch", disconnectors referred to as "knife" in use, both frequently used in combination. 13. Installation of the circuit breaker can be single pole or double pole base loading mode. 0577-62708571,13736777019
