Socket with miniature switching relay; 230 VAC; 16 mA; Relay with 1 changeover contact (1u); with integrated base load module.
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 195.5-253Vac (230Vac nominal) at 50/60Hz, and operates with a 1C/O (SPDT) contact configuration. This electromechanical relay supports a rated current of 6A continuously, 3A at 250Vac (AC-15), and 2A at 24Vdc (DC-13). It includes Push-in CAGE CLAMP connections for easy installation on a DIN-35 rail (6mm width) and has an IP20 protection rating. The contacts are made of Silver-Tin (AgSnO) material, and it is equivalent to the model 857358006000.
