It's rated 16 A at 30 °C with a 10,000 A Icn breaking capacity at 400/415 V (limitation class 3), so it handles fault currents up to that level without cascading upstream in a TN earthing system. The 100 mA earth-leakage sensitivity catches ground faults on three protected poles.
The neutral sits on the left; terminals accept 1–25 mm² rigid or 1–16 mm² flexible with screw clamps (2.5 N·m torque). Strip 11 mm for the bottom connection, 14 mm for the top. IP20 rated, so it's panel-internal only — no washdown exposure. Padlockable with a 4 mm Ø lock or lead seal for lockout/tagout.
Rated for 5,000 electrical cycles and 20,000 mechanical cycles — the thermal-magnetic trip unit is field-reliable for routine switching on outgoing circuits. Toggle control with ON/OFF local indication. Wire stripping lengths differ between top (14 mm) and bottom (11 mm) terminals; mixing them up leaves copper exposed or insufficient contact.
