SW185B-104 single-acting 'Normally Closed' 220Vac contactor continuous.
- The sw185 series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as industrial trucks, airport tractors, etc., they have double-breaking contacts with Silver-alloy contact tips, which are weld resistant, hardwearing and have excellent conductivity.
- Mounting bracket is available: 2159-47.
- Rectifier board fitted as standard.
- Coil insulators fitted.
- Height including terminals and coil base cap: 122mm.
- Coil width: 45mm.
- Cap width: 61mm.
- Cap depth: 45mm.
These contactors are of double break configuration and are fitted with magnetic blowouts (denoted by 'B' suffix in the SU185B 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 Normally Closed (CO.) SW185 Solenoids
Normally Closed continuous contactors by design are for an ‘Always On’ line function and break only when the coil is energised, they make and break slower than intermittent solenoids and are recommended for prolonged contact periods.
Please note: Normally Closed contacts are not suited to make and break load.
