About Highly Intermittent (HO.) SU280 Solenoids
Highly Intermittent Services up to 25% duty cycle and up to 3 minutes continuous energisation. The higher power in the coil allows for a stronger return spring to be used, giving good switching characteristics.
The contactors have double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. They are easy to install, with M5 tapped holes in the switch frame together with a range of available mounting brackets. Mounting can be vertical or horizontal, when vertical the M10 contact studs should point upwards
| Interrupted Current: The opening and closing on load with frequent switching (resulting in increased contact resistance). |
| Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
