The 4-pole auxiliary relays are used for switching auxiliary and control circuits (with forced-guided contacts available). They feature an electronic coil interface that can accommodate a very wide control voltage range. This allows them to handle significant fluctuations in control voltage. They require a very low holding power of only 1.7 W. Auxiliary relays can withstand short voltage drops and dips (according to SEMI F47-0706). They come with built-in overvoltage protection and do not require additional suppression components. Additionally, a wide range of accessories is available.
