1SVR730100R3300

The ABB 1SVR730100R3300 (CT-ERS.22S) 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-S series and provides an ON-delay (delay-on-make) function with 10 adjustable timing ranges covering 0.05 seconds to 300 hours. It operates with a rated control supply voltage of 24–240V AC or 24–48V DC and features two changeover (SPDT) output contacts rated at 250V and 4A. Its wide timing range and dependable switching capability make it suitable for industrial control applications.

The ABB CT-ERS.22S 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 contacts after the selected delay has elapsed. Its two changeover contacts allow flexible integration into suitable industrial control circuits.
