RICH CONTACTOR SIZE A30-40

RICH CONTACTOR SIZE A30-40

A Contactor Size A30-40 is a heavy-duty electromagnetic contactor used to switch high-current electrical loads on and off using a low-power control signal. It is commonly used for three-phase motors, pumps, compressors, lighting circuits, and industrial machinery. The A30–A40 series is designed for motor control and power switching applications.

Uses:

Starting and stopping three-phase electric motors.

Controlling water pumps and borehole pumps.

Switching air compressors and HVAC equipment.

Controlling industrial machinery.

Switching lighting banks and heating loads.

Used in Automatic Transfer Switch (ATS) panels and motor control panels.


Applications:

Factories and industrial plants

Commercial buildings

Pump control panels

Motor control centers (MCCs)

Generator and ATS systems


The A30-40 contactor is designed for frequent switching of electrical loads and is typically used together with an overload relay to provide complete motor protection.
