Today during 'My Automation Education' we are going to talk about definite purpose contactors. They are similar to starters in many ways. Contactors and starters are basically just on/off switches.

What is the difference between a contactor and a starter? 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 electic motor. Contactors are rated by their current in amps while starters are rated by their horsepower capacity and the current they use.

Definite purpose contactors are designed for applications including HVAC, i.e. air-conditioning compressor motor starting. DP contactors are also popular in food equipment, data processing and refrigeration industries. Definite purpose contactors are also generally designed for the intended life cycle of the application.

Marshall Wolf Automation, the only industrial automation distributor you need, carries a great line of low-cost DP contactors from Chint. Give us a call or stop by our website for more information!

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.
