Auxiliary Contactor Delay On Make or DelayTimer for AC/DC contactor 1NO 1NC UT series auxiliary contact blocks are installed on the top of UKC1 series AC contactor for expanding the couples of auxiliary contacts points. IEC utilization categories The current rating of the AC/DC contactor depends on utilization category. Example IEC categories in standard 60947 are described as: AC-1 - Non-inductive or slightly inductive loads, resistance furnaces AC-2 - Starting of slip-ring

Restrain Suppressor Hi Frequency AC Contactor Surge Protector Absorber This suppressor is mainly used in inductive circuit (such as AC contactor), can rise to avoid high voltage, frequency, restrain restrain high surge current and arcing, avoid electromagnetic interference, ensure the normal transmission, and protect the output signal of the electronic equipment. IEC utilization categories The current rating of the AC/DC contactor depends on utilization category. Example IEC

3 Pole 10000A Earth Leakage Mini Circuit Breaker Overload Protection The ELCB is applied to the circuit of AC 50Hz with rated voltage up to 400V, rated current up to 50A, power supply neutral point earthing. It's mainly used to protect person from getting an electric shock and protect the building′s circuit devices from over current, it also can protect the earthing fault. The ELCB is according with IEC61009-1:1991, GB16917.1-1997 standard. Specifications: Technology

50KA Thermal Adjustable Molded Case Circuit Breaker 160A 3 Pole Purple Horn has the Utility Model Patent for the structure of double making & double breaking! The UKM32 series MCCB is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be
