These contactors are fitted with magnetic blowouts across the contact gaps as standard. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. Fitting of blowouts can make the contacts polarity sensitive and the positive markings on the top cover of the contactor must be observed.
About Continuous (CO) SW201-157 Solenoids
Continuous contactors by design are predominantly for drive functions on vehicles, they switch slower than intermittent solenoids and are recommended for prolonged contact periods.
The SW201 has M10 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or mounting brackets purchased as separate items. Mounting can be horizontal or vertical, when vertical the M10 contact studs should point upwards. Please note Normally Closed contacts are not suited to make and break load.
|Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance).|
|Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).|
