Albright SU280-1080P single-acting 80 Volts DC 250 Amps solenoid contactor, protected to IP66, continuous.
- The SU280P has been designed for direct current loads, particularly motors, as used on electronic vehicles such as industrial trucks, airport tractors, etc. They have double-breaking contacts with Silver-alloy contact tips, which are weld-resistant, hardwearing and have excellent conductivity.
- Height, including terminals and coil base cap: 132mm.
- Coil width: 45mm.
- Cap width: 67mm.
- Cap depth: 47mm.
About Continuous (CO.) SU280P Solenoids
Continuous contactors, by design, are predominantly used for drive functions on vehicles; they make and break slower than intermittent solenoids and are 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. 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). |
