The SW120 has been designed for Direct Current loads, typical applications include motors as used on small electric vehicles such as light industrial trucks and powered cars. These contactors are not polarity sensitive thus they can be used for switching Alternating Current loads.
The SW120 features double pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW120 has M8 stud main terminals and 6.3mm spade coil connections. Mounting is via M5 tapped holes or mounting brackets, either supplied fitted, or as separate items. 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.
