9A~85A 3P anti- electric shock Magnetic Power Contactor For Motor
Circuit Protection DC/AC Color optional
GMC1 series magnetic AC contactor is suitable for using in the
circuits up to rated voltage 660V AC 50/60HZ, rated current up to
800A, for making, breaking, frequently starting & controlling
the AC motor and it can be combined with the auxiliary contacts,
mechanical interlocking unit, switchover capacitor and etc. With
the thermal relay, it is combined into the electromagnetic starter.
The contactor is produced according to IEC947-2, VDE0660 &
IEC utilization categories
The current rating of the AC/DC contactor depends on utilization
Example IEC categories in standard 60947 are described as:
AC-1 - Non-inductive or slightly inductive loads, resistance
AC-2 - Starting of slip-ring motors: starting, switching-off
AC-3 - Starting of squirrel-cage motors and switching-off only
after the motor is up to speed. (Make Locked Rotor Amps (LRA),
Break Full Load Amps (FLA))
AC-4 - Starting of squirrel-cage motors with inching and plugging
duty. Rapid Start/Stop. (Make and Break LRA)
1. The cover for preventing electrical shock on the top of ac
contactor and thermal overload relay
2. The ac contactor and relay are classified into 3 frame sizes
according to the external dimensions
3. AC Contactor and relay can be connected directly without other
4. Installed by screws or on the 35mm DIN rail directly

Coil voltage(AC) :
50Hz: 24V, 42V, 48V, 100V, 110V, 220V, 240V, 380V, 400V, 415V,
440V, 500V, 550V
60Hz: 24V, 48V, 110V, 120V, 208V, 220V, 240V, 277V, 380V, 440V,

Working principle of magnetic AC contactor:
when the coil is energized, a static iron core generates
electromagnetic force, will be moving iron core is attracted,
because the contact system and the movable iron core linkage, the
movable iron core drives the three movable contact piece run at the
same time, contact is closed, thereby connecting the power supply.
When the coil is de-energized, suction disappeared, the movable
iron core linkage relies in part on the reaction force of the
springs and the separation, the main contact is switched off, cut
off the power supply. The long distance open and control function.

Selection of AC contactor
Usually pay attention to the following points: there is no smell
smell, please check the winding and contact. Listen to see whether
they have a very loud squeak - sound, such as may be low power
supply voltage and the point of contact with dirt or dynamic and
static iron core contact surface is dirty. If you hear the Kaka -
contactor sucking not sound, for low supply voltage or contact with
After starting up, the contactor is attracted, such as compressor
does not turn, you don't know the contact of a contactor is broken,
please immediately contact the manufacturer for a replacement.
