GK65 серии 1-63A MCB

1. Apllication of GK65 Series 1-63A MCB GK65 Series1-63A MCBare mainly apply to AC 50/60Hz circuit with rated voltage 230V/400V or less, rated current up to 100A and provide circuits of modern buildings with overload and short-circuit protections,and it can also be used for operating and isolating the circuitin frequently. Model D for motor protection. 2. Construction Features of GK65 Series 1-63A MCB GK65 Series 1-100A MCBare composed of the moulded case, operating mechanism, contact system, arc-extinguishing system, tripping mechanism, ete.The case is made of the special plastic high in fire-resistance and strength , so it is very capable of resisting impact and light in weight. The parts ofthe operating mechanism employ high strength plastic products in order to assure the flexible,reliable operation and obtain the minimu mmoment of inertia as well so that the time from the moment the short-circuit fau lto ccurs to the operation of the tripping mechanism is very little. The tripping mechanism is composed of the two parts of bimetal sheet overload counter time limit tripping mechanism and short-circuit instantaneous electromagnetic mechanism.The contact arc-cxtinguishing system employs the special arc-conducting angle and gangway are-extinguishing chamber so it has distinct current limiting characteristics. 3.
