It integrates a 25 A thermal-magnetic MCB (C-curve) and a 30 mA earth-leakage detector in one clip-on DIN-rail unit, saving a full module width versus separate devices. Earth-leakage protection is integrated at 30 mA sensitivity, providing supplementary protection against direct contact and covering the typical requirement for socket-outlet circuits in TN earthing systems. The neutral is switched (1P+N) with the neutral on the left side of the module.
The 18 mm width occupies 2 x 9 mm pitches. Top and bottom screw-clamp terminals accept 1…25 mm² rigid (top) and 1…16 mm² rigid (bottom); tightening torque is 3.5 N·m top, 2 N·m bottom. IP20 finger-safe, IP40 in a modular enclosure. Padlockable with a Ø 4 mm padlock for lockout/tagout. The toggle provides ON/OFF local indication. Wire stripping length is 13 mm (bottom) and 14 mm (top).
Designed and certified to IEC 61009-1 and IEC 61009-2-2, the international standard for RCBOs. Limitation class 3 indicates energy-limiting performance that reduces let-through energy on short-circuit. Suitability for isolation is confirmed. Southeast Asia, coastal plant rooms).
