RELAC 230V, gray.
The WAGO 857 series plug-in relay assembly features a socket base with an ejector, a built-in base load module, and a yellow LED indicator. It is a single-pole (1P) relay with a control voltage range of 195.5-253Vac (230Vac nominal; 50/60Hz; 0.85...1.1 x Uc) and a Single Pole Double Throw (SPDT) contact configuration. The relay is electromechanical in design, with a rated current of 50mA (30Vdc; DC-13) to prevent gold flash evaporation. It includes Push-in CAGE CLAMP connections and is designed for DIN-35 rail mounting with a 6mm width. The contacts are made of hard gold-plated silver-nickel (AgNi + Au) and it is equivalent to model 857368006000, with an IP20 protection rating.

- note:
- To prevent damaging the gold layer, 30 V switching voltages and 50 mA currents must not be exceeded. Higher switching power eventually evaporates the gold layer. The resulting deposits in the housing may reduce service life.To protect the relay coils
