The ABB Time Delay Relay for 415V AC is described as a single-function electronic timer relay, commonly found in the CT-E timer range by ABB. Specifically, the CT-SDE model offers a star-delta function with an adjustable time range from 0.3 seconds to 30 seconds. This relay operates with a rated control supply voltage of 380 to 415 V AC. The device is designed for precise timing control in applications like motor control circuits where a star-delta configuration is needed. It features terminal connection options such as screw terminals or push-in types, and is suitable for DIN rail mounting. The design emphasizes reliable operation under tough conditions with easy installation and precise adjustment via front-face operating elements.
