SU280P

NO - SP - ST - IP66

The SU280P has been designed for direct current loads, particularly motors as used on electronic vehicles such as industrial trucks and airport tractors.

The contactors feature double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.  The SU280P offers greater environmental protection (IP66) and is easy to install, with a range of mounting brackets available.  To ensure IP66, mounting holes are not accessible.  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.
