Data sheet Electronic timer CT-SDE Star-delta change-over with n/c + n/o contact The CT-SDE is an electronic time relay with star-delta change-over. It is from the CT-E range. The CT-E range is the economic range of ABB s time relays and offers a cost effective price-performance ratio for OEM users. This is achieved by simplified functionality and results in the simplest of setup procedures. The CT-E range is ideally suited for repeat applications. CDC 09 F000 Characteristics versions: single time range (0.-0 s) and different rated control supply voltage ranges ( V AC/DC / 0-0 V AC, 0-0 V AC and 80- V AC) Single-function timer with star-delta change-over Starting time (star) adjustable Transition time 0 ms fixed n/c and n/o contact with common contact. mm (0.89 in) width LEDs for the indication of operational states Order data Type Rated control supply voltage Time range Order code CT-SDE 0-0 V AC 0.-0 s SVR 0 0 R00 V AC/DC, 0-0 V AC SVR 0 7 R00 80- V AC SVR 0 R00

Function diagram F Star-delta change-over (Star-delta starting) Applying control supply voltage energizes the star contactor (K) and the line contactor (K) and begins the set starting time. When the starting time is complete, contact - de-energizes the star contactor (K). Now, the fix transition time starts. When the transition time is complete, contact -8 energizes the delta contactor (K).
