The ABB 1SVR550107R4100 is an electronic time relay belonging to ABB’s CT‑E timer family. It provides an ON‑delay (delay‑on‑make) timing function: when control power is applied, the relay will wait for a preset delay before switching its output. The device is compact and DIN-rail mountable, designed for installation in control panels, automation cabinets, industrial control systems, lighting control, or other applications that require delayed switching of loads. It supports a wide range of control supply voltages (both low-voltage DC/AC and standard AC), giving flexibility in integration with different control systems.
