857-358 WAGO Industrial Automation Components

Wago 857-358 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections. It is designed for a rated current of 6A continuous, with specific ratings for different conditions: 3A at 250Vac (AC-15), 2A at 24Vdc (DC-13), and a maximum inrush current of 20A for 20ms at AC. The relay includes a socket base and ejector, a yellow LED, and operates with an electromechanical design. It recommends a minimum switching load of 10V / 10mA / 24V / 1mA. The resistance is specified as 1C/O / SPDT (Single Pole Double Throw) contact. It is designed to operate within an ambient air temperature range for storage of -40°C to +60°C. The rated voltage (AC) spans from 184-253Vdc (230Vdc nominal), with a control voltage (AC) of 4 kV and a rated active power for a single-pole / 1-pole (1P). The relay is colored for 184-253Vac (230Vac nominal), with a protection degree of IP20 and designed for mounting on a DIN-35 rail. Dimensions are H94mm x W6mm x D81mm, indicating a width of 6mm. The primary current contacts are made of Silver-Tin (AgSnO) with a Polyamide (PA) 66 housing. The relay has a switching time of 15ms for contacts closing and 25ms for contacts opening, with a rated impulse voltage (Uimp) of 250 V. It is designed for a lifespan of 50,000 operations under a load and 5,000,000 operations mechanically, within a humidity range of 5-85% RH without condensation.
