858-304 WAGO Signal Relays

Wago 858-304 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections. It is designed to handle a rated current of 5A continuously, with specific ratings for AC-15 at 1A (240Vac) and DC-13 at 2A (24Vdc), and can manage up to 15A AC inrush maximum current for brief periods. The relay operates with a 4C/O or 4PDT (4 Pole Double Throw) contact arrangement and includes a red LED indicator for electromechanical operations. It recommends a minimum switching load of 12V / 100mA. The relay is designed to function within an ambient air temperature range for storage of -25°C to +70°C and offers a degree of protection rated at IP20. Its control voltage ranges from 19.2-26.4Vdc (24Vdc nominal), with a rated impulse voltage of 2.5 kV. The relay's dimensions are 97mm in height, 31mm in width, and 73mm in depth, fitting a DIN-35 rail for mounting. Contacts are made from Silver-Cerium (AgCe) to ensure proper operation, with a rated operating voltage (Ue) and a memory capacity of 250V. It supports up to 100,000 operations for phase-to-neutral and 20,000,000 operations overall. The relay can operate within a humidity range of 5-85% RH.
