Albright RU80B-5089 single-acting 80Vdc 200 Amps solenoid contactor with magnetic blowouts, 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 RU80 is typically used in line contactors or Power Distribution Systems.
- Auxiliary switch kit part number: 2070-124.
- Contact repair kit part number: 2073-361
- Height including terminals and coil base cap: 91mm.
- Coil width: 40mm.
- Cap width: 50mm.
- Cap depth: 49mm.
These contactors are of double break configuration and are fitted with magnetic blowouts (denoted by the 'B' suffix in the RU80B range) across both contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. The fitting of blowouts makes the contacts polarity sensitive and the Positive markings on the top cover of the contactor must be observed.
About Continuous (CO.) RU80 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. They are easy to install, with M4 tapped holes in the switch frame together with an available range of mounting brackets sold separately. Mounting can be vertical or horizontal, when vertical the M8 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). |
