NO - DP - ST

The SU190 is an up-rated variant of the SW190 Series of contactor primarily designed to switch heavy duty D.C. loads, however it is also capable of switching A.C. loads.  The SU190 is suitable for switching Resistive, Capacitive and Inductive loads.  Typical applications include electric motors, hydraulic power packs, winches, speed controllers and Power Distribution Systems.

The contactors feature double pole, double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.  The SU190 is easy to install, with M5 tapped holes in the switch frame or a variety of optional brackets available.  Electrical connections follow industry standards, with M10 main terminal studs and an option for either 6.3mm standard spade terminals or flying leads on the coil assembly.  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.
