The unit clips onto a DIN rail (mounting mode: clip-on, support: DIN rail) and occupies 10 module pitches (90 mm width). The neutral is on the left, and the connection pitch is 18 mm between phases, 9 mm between phase and neutral. Tunnel-type terminals accept 0.75...16 mm² rigid or 0.33...10 mm² flexible conductors, with a tightening torque of 2 N.m and a wire stripping length of 15 mm.
Breaking capacity is 6000 A Icn at 380...415 V AC 50/60 Hz conforming to EN/IEC 61009-2-1. If your point of supply has higher fault current, you'll need a current-limiting upstream breaker or a higher-rated RCBO. The thermal-magnetic trip unit handles overloads via a bimetal strip and short-circuits via a solenoid, both factory-calibrated. Earth-leakage protection is integrated at 30 mA sensitivity — this is the standard threshold for personal protection against indirect contact (touch voltage). The device trips on both residual current and overcurrent, so it replaces a separate MCB + RCCD combination in one DIN-rail slot.
