It's designed to switch control signals and auxiliary loads in motor control centers and panel builds — think signaling the PLC that a main contactor has picked up, or interlocking a sequence. The 4 NO contacts are rated 10 A at 24 V, 6 A at 230 V, and 1 A at 690 V, which covers most control-circuit voltages you'll find in a 400 V panel.
The S00 footprint is 45 mm wide by 57.5 mm high by 111 mm deep — tight enough for dense panels. Wire termination accepts 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² solid.
Surge suppression is built in via a varistor across the coil terminals. That saves you an external suppressor module and the labor to wire it — one less thing to forget on a midnight startup.
