Three Phase Motor Protection AC Contactor And Relays 180A 3 Pole

Description:

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.

Characteristics:

1. 3 pairs of main contacts: 85% Ag

2. Enclsoure: fire- retardant

3. Button: resin (bearing temperature more thant 250 degree)

2. Fixed by screw

3. AC/DC coil

4. Wide coil voltage

5. Be connected with the thermal overload relay directly

Features:

1. Convenient usage: it is not necessary to dismantle auxiliary contact block and the auxiliary contacts are workable for 100A-220A contactors

2. Withdrawable coil: it is easy to replace the coil and there is no need to disassemble the contactors

3. Various auxiliaries including contacts, delay unit, mechanical interlock unit
