DIODE SW688P
MOTOR REVERSING
The SW688P is a miniature series single pole, free standing, compact contactor which is sealed to IP66. The SW688P has been designed for Motor Reversing applications with direct current loads, particularly motors as used on small traction motors, hydraulic power packs and small electric winch motors. Developed for both interrupted and uninterrupted loads, it is suitable for switching Resistive, Capacitive and Inductive loads.
The SW688P features paired double pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW688P incorporates an enclosed top cover and offers environmental protection to IP66. The SW688P has M6 stud main terminals and 6.3mm spade coil connections. Mounted using supplied brackets, or as separate items. Mounting can be on the side or base of the contactor.
