2 DP - Definite Purpose Control AC Contactors Application Definite Purpose Contactors are intended for use in applications where the control requirements are well defined. They are not recommended for general industrial use. As a magnetic motor controller, they are inductively rated for both maximum continuous current and maximum locked rotor current Resistive ratings apply to resistive heating applications only. Joslyn Clark definite purpose contactors have been specifically designed for use with air conditioning, heating and refrigeration control equipment. They are suitable for other non cycling duty applications requiring reliable low cost switching. Low Coil Inrush and Sealed Provides maximum efficiency, permitting potential cost savings on transformer requirements. This efficient magnet system assures clean pick-up and drop-out without chattering when subjected to slowly rising and slowly decreasing voltages. Versatile Operating Positions Joslyn Clark pole contactors are designed to operate effectively in the vertical, horizontial or tabletop mounting positions. This gives design engineers maximum versatility for designing low cost systems. Interchangeable Along with being compact in size, the mounting plate is designed to facilitate proper alignment and interchangeability with practically all competitive pole contactors. Also, the low v-a permits direct interchangeability without requiring a transformer change. Terminals As an optional feature, Joslyn Clark contactors can be supplied with pressure clamp terminals which are UL Recognized for field connections of # through #8 copper wire. They may also be supplied with box lugs for # through # Al/ Cu wire. Up To A-C Rating The pole contactors have been designed with the customer in mind. They provide clearance between terminals permitting total utilization of all quick connects without requiring special insulation between terminals on equipment rated up to volts.
