EasyHeat® special purpose magnetic contactors are designed for the control of electric heating or snow melting equipment. Magnetic contactors connect and disconnect power supply and load in response to the closing and opening of a pilot control contact (thermostat, switch, snow sensors etc.). They provide dependable full voltage control of resistance heating loads. These controls are available in six ratings from 40 to 112 A non-inductive at 120 to 480 V. All contactors are 3 pole, with coil voltages of 120 and 208/240 available.

EasyHeat® Special Purpose Magnetic Power Contactor, Series: PC Series, 120 VAC Coil, 50 A Maximum Load Current, 3 Pole, NEMA Type 1 Enclosure, Vertical Surface Mounting, 5 in W x 4 in D x 8-5/8 in H Dimensions

• Compact: Space saving dimensions mean smaller panels and more wiring room
• Straight through wiring line terminals are located at the top, load terminals at the bottom
• This construction eliminates the necessity of looping wires around the control and reduces wiring costs
• Contactors are designed for mounting on a vertical surface
• Side by side grouping is possible since all terminals are front accessible and isolated from adjacent controls by molded barriers
• The control can be fastened on a panel by using a combination of multiple mounting holes and slots provided
• Terminals: Line and load terminals are supplied with pressure connectors
• Pilot control wires can be attached to the line terminals by using integral auxiliary quick connectors
• Arc box molded of glass filled thermosetting material, it withstands arc tracking and prevents flash over
• Contacts made of silver cadmium oxide that resists welding, arc erosion and mechanical wear, these critical components are bonded to rugged backing material
• Encapsulated in a moisture proof epoxy that resists mechanical, electrical and thermal stresses, the coil also serves as a guide for the moving armature assembly
• It is equipped with terminals having both pressure and quick connectors
• Connections may be made either by inserting the stripped wire under the screw head and tightening or by pressing on a quick connector
• They pull in with a maximum of 85% rated volts and drop out at approximately 60% of rated volts
• The ampere ratings shown in the table are for continuous duty on resistance heating loads
• Enclosure Contactors are supplied in a NEMA type 1 general purpose enclosure, this enclosure protects personnel from accidental contact with electrical apparatus
• It meets the needs of indoor applications in normal atmosphere free of excessive moisture, dust and explosive materials
