Electric Heat Pump Contactor 100A , Mechanically Interlocked Contactors

Electric Heat Pump Contactor 100A , Mechanically Interlocked Contactors

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

Features:
