The ABB 1SVR550110R4100, type CT-AHE, is a compact and reliable electronic time relay designed for accurate time-delay switching in industrial automation and electrical control applications. Part of the ABB CT-E timer relay range, it provides an OFF-delay timing function for machinery, control panels and automation systems requiring dependable sequence control.
The CT-AHE provides an OFF-delay (delay-on-break) timing function with an adjustable time range of 0.3–30 s. It operates from a 110–130 V AC control supply and includes a single changeover output contact, making it suitable for a wide range of industrial timing applications.
With a compact 22.5 mm DIN rail mounting design, a 1 c/o (SPDT) output contact rated at 250 V / 4 A and screw terminal connections, the ABB CT-AHE provides a practical timing solution for OEM equipment, automation systems and industrial electrical installations.
Electronic timer relays such as the ABB CT-AHE provide precise timing control for electrical circuits by maintaining output operation for a defined period after the control signal is removed. The OFF-delay function allows equipment sequences to be controlled accurately, improving automation reliability.
The ABB CT-E timer range combines compact dimensions, simple adjustment and dependable switching performance, making the CT-AHE suitable for industrial machinery, electrical control panels and OEM automation applications.
