Motor Protection Circuit Breaker AC Contactor Magnetic 24V 110V 220V 380V 1NO or 1NC
Description:
The power consumption of the UKC1- low consumption type contactor is 1.2W.
Low coil power consumption greatly expands application flexibility. Standard AC coils require 1.8 watts.
Directly drive contactor by transistor output of PLC
This contactor can be driven by a transistor output of a PLC or electronic equipment such as photoelectric switch, or a proximity limit switch. Therefore, it is possible for this contactor to directly interface without interface relay for driving a 3-phase induction motor.
AC Contactors (Magnetic Contactor) provide remote control of primarily electric motors and compensation & heating systems by cable. They protect the instruments and equipments against overload currents by using thermal relays, for capacitor switching contactor.
While switching on a capacitive circuit, a high frequency and large transient current peaks are produced. Switching of capacitor for a single or one of the capacitor banks are different from each other. Step by step "switching on" operation is more difficult for contactor than capacitor bank. Because during this operation for capacitor bank, compensated current occurs. For this reason selecting of suitable contactors the compensating current must be take into consideration for 50kVAR and above, and for less than 50kVAR can be omitted.
