Design Of The Productfor motor protection

Product details

The 45 mm width (3-module) fits standard enclosure rail spacing. Screw-type terminals on both main and auxiliary circuits; solid wire from 0.5 to 2.5 mm² and stranded from 1 to 6 mm² are accepted. AWG 14–10 for the main contacts. No side or backward clearance required — zero spacing above or beside the unit — so it can pack tightly against adjacent devices.

Auxiliary Switch and Ratings

The auxiliary switch is transverse design and field-addable (product extension auxiliary switch: yes). Contact ratings: 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V. These are the switching currents for the signal contacts — useful for feeding a PLC input or a status lamp.
