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. • Interrupted current - opening and closmg on load with fréquent switching (results in increased contact résistance).

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. 131 [5.151 M5 MOUNTING HOLES (4 OFF PER SIDE) Dimensions in mm [inches] SU190 Available Options General Auxiliary Contacts X Auxiliary Contacts - V3 X Magnetic Blowouts* X Magnetic Blowouts - High Powered* o Armature Cap • Mounting Brackets (see SW180 Series Catalogue) o Magnetic Latching (Not fail safe)* o Closed Contact Housing X Environmentally Protected IP66 X EE Type (Steel Shroud) o Contacts Large Tips X Textured Tips o Silver Plating X Coil AC Rectifier Board (Fitted) o Coil Suppression* o Flying Leads o Manual Override Operation X M4 Stud Terminals X M5 Terminal Board o Vacuum Impregnation o Key: Optional o Standard • Not Available X * Connections become polarity sensitive SU190 Contactor Performance 1 1 1 1 1 1 Figures are for guideline - ji pu SCS l_ a" <a* <*> ^ Current (Amperes) Contact Performance Key: Interrupted Current - Uninterrupted Current Performance data provided should be used as a guide only.
