The unit occupies 4 modular pitches of 9 mm (72 mm total width) on the rail. Bottom tunnel terminals accept 1 to 35 mm² rigid cable or 1 to 25 mm² flexible cable, with a tightening torque of 3.5 N.m and a strip length of 14 mm. IP20 rated on the front face; IP40 within a modular enclosure.
Electrical ratings and protection characteristics
Insulation voltage is 500 V AC, with an impulse withstand voltage of 6 kV. The residual current tripping technology is voltage-independent — the device does not require an external power supply to detect leakage and trip, which means it remains functional even if the line voltage drops. Earth leakage protection is instantaneous (no intentional time delay). The device complies with EN/IEC 61009-1 and EN/IEC 61009-2-1, and carries a pollution degree 3 rating per IEC 60947-2, suitable for industrial environments where conductive pollution may occur.
