857-154 WAGO Signal Relays

Wago 857-154 is a replacement plug-in basic relay designed for various automation applications. It features an electromechanical design with a rated current of 6A continuous, 3A at 250Vac (AC-15), 2A at 24Vdc (DC-13), and a maximum inrush current of 20A for 20ms at AC. The relay operates with a single pole double throw (SPDT) contact configuration and recommends a minimum switching load of 10V / 10mA / 24V / 1mA. It is designed to withstand an ambient air temperature range for storage from -40°C to +85°C and offers a degree of protection rated at IP20. The control voltage is specified at 48Vdc, with a rated voltage for AC applications at 250Vac max. and a mounting mode of single-pole / 1-pole (1P). The relay's dimensions are H15mm x W5mm x D28mm, and it features silver-tin (AgSnO) contacts. The operating speed for contacts closing is 8ms and for contacts opening is 4ms. It is designed for a rated operating voltage (Ue) with a mechanical life expectancy of 50,000 operations and an electrical life of 5,000,000 operations. The relay operates efficiently within a humidity range of 5-85% RH, with no condensation permissible.
