Albright RU280B-5176P single-acting 36-48VDC 350 Amps solenoid contactor, intermittent.

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 RU280 is typically used in line contactors or Power Distribution Systems.
Due to the configuration of this contactor no repair/contact kit is available.
No bracket fitted.
All holes on the bottom cover are knocked out.
The Contactor is not sealed - Does not meat IP66.

About Intermittent (Int.) RU280 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. They are easy to install, with M5 tapped holes in the switch frame together with a range of 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).
