The WAGO 857 series plug-in relay assembly features a socket base and ejector with a yellow LED indicator. It is a single-pole (1P) relay with a control voltage range of 16.8-253Vac (24Vac, 120Vac, 220Vac, 230Vac nominal; 50/60Hz; 0.7...1.1 x Uc) and 16.8-253Vdc (24Vdc, 120Vdc, 200Vdc, 220Vdc, 230Vdc nominal; 0.7...1.1 x Uc). The relay has a Single Pole Double Throw (SPDT) contact configuration and an electromechanical design, with a rated current of 6A continuous, 3A at 250Vac (AC-15), and 2A at 24Vdc (DC-13). It includes Push-in CAGE CLAMP connections, is designed for DIN-35 rail mounting with a 6mm width, and has an IP20 protection rating. The contacts are made of Silver-Tin (AgSnO), and it is equivalent to model 857359.
