KRIPAL GMC UKC1-16M 6A,9A,12A,16A 1NO or 1NC AC Mini Contactor Motor Protection Switch Low consumption
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.

Benefits for mini AC contactors:
Low consumption power
Saving panel size
Installation space is reduced to 50% of conventional DC operated contactors achieving high performance.
Main application fields for ac mini contactors:
Lighting for out-door
Car washing facilities
Crain hoist
Lighting of sports facilities
Pump
Compressor
Vending machine
Painting machine
Show case
It is possible to expand the control wire length since voltage drop in wires is small.
Application:
Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.
Lighting control
Contactors are often used to provide central control of large lighting installations, such as an office building or retail building. To reduce power consumption in the contactor coils, latching contactors are used, which have two operating coils. One coil, momentarily energized, closes the power circuit contacts, which are then mechanically held closed; the second coil opens the contacts.
