288-437 WAGO Industrial Automation Components

Wago 288-437 is a plug-in relay assembly featuring CAGE-CLAMP spring connections. It operates with a rated current of 50mA at 30Vdc (DC-13) for maximum recommended current to avoid evaporating the Gold flash and 5A continuously. This electromechanical design includes Normally Open (NO) auxiliary contacts on a socket base and supports a 0.1V / 0.1mA / 1mW recommended minimum switching load. The rated power is defined as 2C/O / DPDT (Double Pole Double Throw) contact. It is designed to operate within an ambient air temperature range of -25°C to +70°C. The control voltage (DC) and rated voltage (AC) are specified as -25°C to +70°C and 250Vac max. (switching voltage), respectively, with a rated impulse voltage (Uimp) of 20.4-26.4Vdc (24Vdc nom.). The relay's dimensions are specified with a net width of 19mm and a mounting mode on a DIN-35 rail. The contacts are made from Hard Gold-plated Silver-Nickel (AgNi + Au), ensuring durability and a reliable connection. The operating and storage temperature ranges are conducive to a variety of environments, and the relay is capable of 100,000 operations phase-to-phase with a power dissipation/losses capacity of 50,000,000 operations. It is recommended for use in conditions with 5-95% relative humidity (RH).
