DQ3 Magnetic Starter is designed for reliable control and protection of electric motors in low-voltage industrial applications. Suitable for circuits up to 660V AC (50/60Hz), it supports motor control power up to 45kW with a current rating of up to 95A.
The DQ3 enables direct start and stop of motors and, when combined with a thermal overload relay, provides effective protection against overload and phase failure, helping extend motor service life and reduce downtime. Manufactured in compliance with IEC/EN 60947-4-1, it meets international standards for motor control equipment.
Ideal for manufacturing plants, pumping systems, HVAC installations, conveyors, and industrial machinery, the DQ3 Magnetic Starter delivers dependable performance, operational safety, and long-term reliability in demanding environments.
DQ3 series magnetic starter is suitable for using in the circuits the rated voltage up to 660V, AC 50Hz or 60Hz, rated control power to 45kW and current to 95A. It is used to control the direct start and stop of the motor, and the starter with thermal overload relay protects the motor from overload and phase failure.
Standard: IEC/EN 60947-4-1
3.1Altitude: � 2000m;
3.2Ambient air temperature: -5″C ~ +40″C, average temperature of 24 hours must below+35″C;
3.3Relative humidity: the maximum temperature of 40 degrees, the air relative humidity not exceed 50%, at a lower temperature can allow for a higher relative humidity. The wettest month’s average lowest temperature must be below 25°C, the max relative humidity of that month should not exceed 90%. If humidity changes as a result of occasional gel generated, should eliminate it.
3.4Installation position: The installation degree of the tilt and vertical plane should not exceed 5° ;
3.5In a non-explosive hazardous medium, and there is no place in the medium that is sufficient to corrode metals and destroy insulation gases and conductor dust.
3.6Where there is rain and snow protection and there is no steam.
3.7Shock vibration: Products should be installed and used without severe shake, shock and vibration of the place.
