858-303 WAGO Signal Relays

Wago 858-303 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections for efficient setup. It operates with a rated current of 5A continuously, with specific ratings for different conditions: 1A at 240Vac (AC-15), 2A at 24Vdc (DC-13), and a 15A AC inrush maximum current for brief periods. The relay is designed with a socket base, includes a red LED indicator, and is built with an electromechanical design. It recommends a minimum switching load of 12V / 100mA. The relay supports a 4C/O or 4PDT (4 Pole Double Throw) contact arrangement, ensuring versatility in connection options. It is designed to operate within an ambient air temperature range for storage of -25°C to +70°C and offers a degree of protection rated at IP20. The control voltage ranges from 9.6-13.2Vdc (12Vdc nominal), with a net width of 31mm, and it is designed to be mounted on a DIN-35 rail. The relay features Silver-Cerium (AgCe) contacts for improved conductivity and durability, with a rated operating voltage (Ue) and a quick response time for contacts closing and opening at 25ms. It is capable of enduring up to 100,000 operations for phase-to-neutral and 20,000,000 operations overall, suitable for environments with 5-85% relative humidity (RH).
