Definite purpose contactors are ideal for heating, air conditioning (HVAC), refrigeration and food and beverage equipment.  They have become popular for electric motors, lighting, compressors and much more. 

So what is the difference between a contactor and a starter? A manual motor starter is basically an ON-OFF switch with overload protection. A manual motor starter is a motor controller that operates from a toggle handle or push button that is operated by hand.  A contactor is an electrical switch used for switching current on and off in a circuit without overload protection.

A starter is usually an assembly, that includes a contactor plus an overload relay, used to start an electric motor.  Contactors are rated by their current in amps while starters are rated by their horsepower capacity and the current they use.  They are also generally designed for the intended life cycle of the application.

Manufactured by Chint,  these are generally easily interchangeable with other dp contactor brands including Eaton contactors, Schneider, Dayton and Furnas/Siemens.
