The SW182 has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW182 is suitable for switching Resistive, Capacitive and Inductive loads.
The SW182 features single pole double throw, double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW182 has M8 stud main terminals and 6.3mm spade coil connections. The main contact circuit, designed for motor reversing, is such that it has a built in fail safe, so that if both coils are energised simultaneously the contact arrangement is open circuits. 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.
Note Normally Closed contacts are not suited to make and break load.
