The integrated 30 mA earth-leakage protection means it covers both overload/short-circuit and ground-fault detection in one DIN-rail unit, saving a module width versus separate MCB + RCD. Breaking capacity is 4.5 kA Icn at 230 V AC, 50/60 Hz, conforming to EN/IEC 61009-2-1 — adequate for residential and light commercial sub-distribution boards where the prospective fault current stays under that threshold. Thermal-magnetic trip technology gives a time-delayed thermal response for overloads and an instantaneous magnetic response for shorts. Limitation class 3 means the device limits let-through energy in a fault — relevant for downstream cable protection and coordination with upstream devices.
Clip-on mounting to a DIN rail, 36 mm width (4 x 9 mm pitches), 85 mm height, 73 mm depth. Tunnel-type terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible cable; strip length 14 mm, tightening torque 2 N·m. IP20 on the front face, IP40 inside the modular enclosure — standard for distribution boards.
Certified to EN/IEC 61009-2-1 with KEMA-KEUR and VDE quality marks. Electrical durability 20,000 cycles, mechanical durability 20,000 cycles. Local signalling provides ON/OFF indication and fault indication on the toggle.
