A definite purpose (DP) contactor is an electronically-controlled switch designed for use with switching power circuits. These contactors were initially designed for a specific purpose, hence the name "definite purpose."
To understand DP contactors, it's essential to understand the basics of a contactor.
First, contactors are electromechanical devices that regulate the switches of loads connected across them. In these systems, the contactor changes its contact state from open to closed when the coil is energized, causing the equipment to turn ON.
Unlike a general purpose contactor, definite purpose contactors are smaller but have similar ratings. In addition, DP contactors are UL-recognized instead of listed and offer greater compatibility. These contactors are ideal for specific scenarios and are often chosen for such, as they're widely compatible and available at a lower price.
