857-304 WAGO Automation components

About the product: Wago 857-304 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections. It is designed to handle a rated current of 6A continuously, 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 offers a socket base and ejector, a yellow LED indicator, and operates on an electromechanical design. It recommends a minimum switching load of 10V / 10mA / 24V / 1mA. The relay has a 1C/O / SPDT (Single Pole Double Throw) contact configuration, with an ambient air temperature for storage ranging from -40°C to +60°C. It provides a degree of protection rated at IP20 and has a net width ranging from 20.4-28.8Vdc (24Vdc nominal). The control voltage for DC is specified as 0.85...1.2 x Uc, with a rated impulse voltage (Uimp) of 4 kV. The relay's dimensions are H94mm x W6mm x D81mm, featuring silver-tin (AgSnO) contacts. It is designed for a single-pole / 1-pole (1P) configuration and can be mounted on a DIN-35 rail. The rated operating voltage (Ue) and the switching times for contacts closing and opening are both 8ms / 0.008 s. It is rated for 250 V, with a mechanical life expectancy of 50,000 operations and an electrical life of 5,000,000 operations. The relay operates within a humidity range of 5-85% RH, with no condensation permissible.
