- Cap depth: 45mm.
Magnetic Blowouts
These contactors are fitted with magnetic blowouts (denoted by 'B' suffix in the SW84B range) across contact gaps. 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 Intermittent (Int.) SW180 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 SW180 has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW180 is suitable for switching Resistive, Capacitive and Inductive loads.
The SW180 features single-pole, single-throw, double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW180 has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or steel mounting brackets (supplied as separate items). Mounting can be horizontal or vertical. 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). |
