SW88

MOTOR REVERSING

The SW88 has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks.  Developed for both interrupted and uninterrupted loads, the SW88 is suitable for switching Resistive, Capacitive and Inductive loads.

The SW88 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.  The SW88 main contact circuit, designed for motor reversing, is such that it has a built in failsafe, so that if both coils are energised simultaneously the contact arrangement is open circuits.  The SW88 has M8 stud main terminals and 6.3mm spade coil connections.  Mounted using supplied brackets, mounting can be horizontal or vertical, when vertical the M8 contact studs should point upwards.  If the requirement is for downwards orientation we can adjust the contactor to compensate for this.
