The 48 series is a non-reversing contactor with a 4 normally open, double make contacts rated up to 3HP. It uses a solenoid type moving core design which generates high contact forces. The coil is encapsulated for complete protection. Screw terminals are standard. Available as an option is a SPDT,15 Amp, snap switch, auxiliary contact.

Additional contact configurations and coil options are available – please use the RFQ/RFI tab above to submit your request.
