1SVR508100R0000

The ABB 1SVR508100R0000 (CT-ERC.12) is a high-quality single-function electronic ON-delay 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 ON-delay (delay-on-make) 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 design makes it suitable for industrial installations requiring accurate and dependable time-controlled switching.The ABB CT-ERC.12 ON-delay timer relay is designed for applications where electrical equipment must be activated after a predetermined time interval. When the control supply voltage is applied, the relay begins its timing cycle and switches the output contact after the selected delay has elapsed. Its adjustable timing settings provide flexibility for different industrial operating requirements.
