788-166 WAGO Signal Relays

Wago 788-166 is a replacement plug-in basic relay designed for continuous operation at a rated current of 16A and can handle 6A at 250Vac (AC-15) and 2A at 24Vdc (DC-13), with a maximum inrush current of 30A for 4 seconds. It features an electromechanical design with 1C/O or SPDT (Single Pole Double Throw) contact configuration, recommended for a minimum switching load of 12V / 10mA. The relay operates within an ambient air temperature range for storage of -40°C to +85°C and offers a degree of protection rated at IP40. It is designed for a control voltage of 110Vdc and a maximum switching voltage of 250Vac. The mounting mode is single-pole / 1-pole (1P), and it has a compact size with dimensions of H15.7mm x W12.7mm x D29mm. The relay's contacts are made of Silver-Nickel (AgNi 90/10) for durability, and it has a net width of 110Vdc. The operating speed for contacts closing is 8ms and for contacts opening is 6ms, ensuring quick response times. It is rated for 30,000 operations phase-to-phase and has a power dissipation/losses rating of 30,000,000 operations, indicating its capability for extensive use.
