Product details

That makes it a fit for general-purpose socket circuits and lighting loads where no DC or pulsed DC fault content is expected.

DIN-rail integration and panel fit

IP20 body rating — fine for a dry indoor panel; the modular enclosure bumps that to IP40. Biconnect terminals accept up to 35 mm² rigid or 25 mm² flexible cable, with a 3.5 N.m tightening torque and 14 mm strip length.
