Application:
The contactor covered with a dust cover greatly improves the
service life and Pull-in time of the product, thereby better
protecting the equipment.It mainly applies to the circuit of AC 50Hz/60Hz, and rated
insulation voltage 660V. When used in AC-3, and rated voltage is
380V, rated current up to 620A, for long distance breaking circuit
and frequently starting or control the motor. Combined with proper
thermal overload relay can protect load circuit. Contactor can
frequently start and control AC electromotor.
