Single-phase Motor Start up Reactors
- Single-phase motor start up reactors built according to IEC 61558-2-20
- Three-phase operating voltage 400V
- Designed for 3 startings per hour, of 5 secs. each
- 30% voltage fall, for a 70% reduced motor starting
- Class H total high casehardening varnish dipped and oven dried
- Particularly indicated for submerged pump startings;
- also useful for transformer connection take-off reduction
- Different starting values, voltages and powers are available upon request
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.
