It protects a single outgoing circuit (distribution application, outgoer position per) against overload, short-circuit, and earth leakage, all in one clip-on DIN-rail unit. The thermal-magnetic trip unit gives the C-curve response (magnetic tripping at 5...10 x In,), and the integrated earth-leakage protection is fixed at 10 mA sensitivity.
Rated 16 A with a 4500 A Icn breaking capacity at 230...240 V AC, 50 Hz per EN/IEC 61009-2-1. The 10 mA sensitivity suits circuits requiring a low leakage threshold.
Clip-on mounting onto standard DIN rail. The module occupies 4 x 9 mm pitches — 36 mm wide, 85 mm tall, 73 mm deep. Single terminal top or bottom accepts 1...16 mm² rigid or 1...10 mm² flexible cable; wire strip length is 15 mm, tightening torque 2 N.m. Neutral is on the left. IP20 on the device body, IP40 inside a modular enclosure — so it's a panel-mount part, not for wet locations without an outer enclosure.
Designed to EN/IEC 61009-2-1. Relative humidity 95% at 55 °C. Local signalling shows ON, OFF, and fault trip. Electrical and mechanical durability both rated at 20,000 cycles.
