The RTA/100 Family is designed for reduced operating periods, thus suitable to limit
inrush currents to values, which do not activate over-current device protection, both for
motors and transformers.
Once the operating period has elapsed (5” max. for motors and 1” for transformers) the
reactors have to be short-circuited to avoid line fall and overheating.
