Power relays

Easy to use electromechanical relays with switching capacities from 2A up to 120A for mounting directly on a PCB.

Energy-efficient high power switching

A line-up of more than 30 series covers nearly all industrial, building and white goods applications. Including devices that handle ≤120A on a PCB, devices with a low profile of 10mm and slim 6mm slim styles, there is a relay for any requirement. All standard versions feature a low power consumption,but the sophisticated, polarized latching types beat all other switching solutions by offering power consumption down to 0W for both On and Off states.
