Eberle Controls Storage Relay SPR 490 70, 230 V AC, 16 A, 1 NO, DIN Rail

The Eberle Controls Storage Relay SPR 490 70 is a high-quality latching relay (impulse relay) designed for reliable switching of lighting and other loads in building installations. With a compact 1 TE (18 mm) width for DIN rail mounting, it offers a rated switching current of 16 A and a control voltage of 230 V AC. Ideal for storage heating systems, lighting control, and similar applications where a maintained switching state is required without continuous power consumption.

Advantages

Energy-efficient latching mechanism eliminates continuous power draw, reducing operating costs. Compact design saves space in distribution boards. High switching capacity supports a wide range of loads including incandescent, halogen, fluorescent, and LED lamps. Robust screw terminals ensure secure and easy wiring.
