 Albright RU280-5078P single-acting 72Vdc 350 Amps solenoid contactor, protected to IP66, continuous.

  • The Reduced Silver series are suitable for applications where infrequent switching is specified. In such applications the degradation of the tip is minimal and therefore a higher volume of silver is unnecessary.
  • Developed for Uninterrupted current applications the RU280P is typically used in line contactors or Power Distribution Systems.

  • Height including terminals and coil base cap: 132mm.
  • Coil width: 45mm.
  • Cap width: 67mm.

About Continuous (CO.) RU280P 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 RU280P offers greater environmental protection (IP66) and is easy to install, with M5 tapped holes in the switch frame together 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).
