Definite Purpose Contactor

Power saving Air Conditioning Contactors 4 Pole AC Contactor 125A 150A

Description:

Magnetic AC Contactor should have the high current value without being exposed to and damaged or boiling. This belongs to the quality of contactor. (Contact surface quality and weld technology) Especially at AC-3 and capacitor command, selectivity of contactor is very important.

Current which passes through the contacts causes warming when the contactor is closed. This warming is limited with the standards. For IEC60947-4-1 when continual thermal current (Ith) is passed though the main contacts, maximum increasing temperature should not exceed 65k.

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

Specifications:

Advantages:

1. Power saving: 5% of traditional power consuming.

2. Long life: short arc duration, little contactor ablation, contactor does not quiver when voltage fluctuates.

3. Reliable coils will not be burnt which are reeled in our own workshop

4. No noise during working

5. There is no temperature rising in the coil control.

6. Not influenced by network voltage fluctuation.

7. Plastic are fire-retardant and the button is resin which can bear temperature more than 200 degree Celsius
