The SU280 has been designed for direct current loads, particularly motors as used on electronic vehicles such as industrial trucks and airport tractors.

The contactors have double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.  They are easy to install, with M5 tapped holes in the switch frame together with a range of mounting brackets.  Mounting can be vertical or horizontal, when vertical the M10 contact studs should point upwards.  If the requirement is for downwards orientation we can adjust the contactor to compensate for this.
