The CS3-40E Coil Control Relay is a three-pole Sprecher + Schuh control relay with a 20 A per-pole contact rating and a high-voltage AC coil configured for 440–480 VAC operation. A CS3-40E-48 variant confirms the 480 VAC coil option, aligning with other CS3-40E models in the family. This device is used to switch three-phase loads in industrial control panels, providing a single relay solution to energize or de-energize multiple conductors in a single action.
