Magnetic Blowouts

 The contactors are double-break and fitted with magnetic blowouts across both contact gaps as standard. 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 Prolonged (PO.) SW200 Solenoids

 Prolonged (PO) use, up to 90% duty cycle and up to 54 minutes of continuous energisation. The coil is more powerful than continuous and weaker than intermittent equivalent. The return spring is stronger than continuous but weaker than intermittent.

 The SW200 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 SW200 is suitable for switching Resistive, Capacitive and Inductive loads.

 The SW200 features single-pole, single-throw, double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW200 has M10 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 M10 contact studs should point upwards.
