SW66

MOTOR REVERSING

The SW66 is a miniature series single pole, free standing, compact contactor designed for motor reversing.  Devised for both interrupted and uninterrupted loads, the SW66 is suitable for switching Resistive, Capacitive and Inductive loads.  Typical applications include switching small traction motors, hydraulic power packs and small electric winch motors.

The SW66 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.  The SW66 has M6 stud main terminals and 6.3mm spade coil connections.  It can be mounted via M4 tapped holes or mounting brackets, either supplied fitted, or as separate items.  Mounting can be on the side or base of the contactor.
