About Intermittent (INT.) SU280P Solenoids
Intermittent contactors, by design, are predominantly used for hydraulic functions on vehicles; they make and break quicker than continuous solenoids and are not recommended for prolonged contact periods.
The contactors have double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing 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 on the opposite side of the mounting bracket. 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). |
