1SVR508130R0000

The ABB 1SVR508130R0000 (CT-VWC.12) is a high-quality, single-function electronic Impulse-ON timer relay designed for industrial automation, electrical control panels, machinery control systems, and time-dependent switching applications. Manufactured by ABB, this timer belongs to the CT-C series and provides a reliable Impulse-ON (interval timing) function with seven adjustable timing ranges covering 0.05 seconds to 100 hours. It operates with a rated control supply voltage of 24–240V AC or 24–48V DC and features one changeover (SPDT) output contact rated at 250V and 4A. Its compact construction makes it suitable for industrial installations requiring dependable time-controlled switching. The ABB CT-VWC.12 Impulse-ON timer relay is designed for applications where an electrical output needs to remain activated for a predetermined period after the control supply is applied. When the supply voltage is connected, the output relay energises immediately and remains active for the selected time interval.
