SW688

PAIRED NO - DP - ST

The SW688 is a miniature series double pole, free standing, compact contactor.  It is 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, the SW688 is suitable for switching Resistive, Capacitive and Inductive loads.

The SW688 features double pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.  The SW688 has M6 stud main terminals and 6.3mm spade coil connections.  Mounted using supplied brackets, mounting can be horizontal or vertical, when vertical the M6 contact studs should point upwards.  If the requirement is for downwards orientation we can adjust the contactor to compensate for this.
