About Intermittent - Intermittent SU280 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 available mounting brackets. Mounting can be vertical or horizontal, when vertical the M10 contact studs should point upwards

Magnetic Blowouts These contactors are of double break configuration and are fitted with magnetic blowouts - denoted by 'B' suffix in the SU280B range) across both contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. 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.)
