- Designed for direct current loads, typical applications include motors as used on small electric vehicles such as light industrial trucks and powered cars.
- Developed for both interrupted and uninterrupted loads, the SW120 is suitable for switching Resistive, Capacitive and Inductive loads.
- The SW120 DC Contactor is not polarity sensitive thus they can be used for switching Alternating Current loads.
- M8 stud main terminals and 6.3mm spade coil connections.
- Adaptable Mounting options, in any orientation (seek technical advice for full mounting considerations).
Spare Parts – Please consult our Technical Department, or download Spare Parts Sheet where available.
