2. Add on blocks

1. Surge suppressor

It is used to reduce the effect of switching overvoltages created

during the opening of inductive circuits. Typically they are

mounted outside the body of the contactor relay, and are

connected in parallel with the coil terminals. Various

techniques for the suppression of switching overvoltages can

be employed. For example: RC element, Varistor etc
