Technical Info
Time Delay Relay for SC-Twin
SD 117N0001, 220-240V, 50 & 60Hz
Introduction
The time delay relay type SD is designed for staggered start of two compressors in the Twinversion as the one-phase mains cannot normally be loaded with the total starting current of both compressors.
When the time delay relay is used, first one compressor is started, and about 10 seconds later the second compressor is started. This ensures the best possible characteristics and the least load on the mains.
The time delay relay has the following specification:
