It protects a 16 A final circuit against overload, short-circuit (B curve, 6 kA breaking capacity per EN 60898-1 and IEC 60947-2), and series/parallel arcing faults that a standard MCB cannot detect. Rated 230 V AC, 50 Hz, 1P+N, two poles. The B tripping characteristic means it will trip at 3 to 5 times rated current (48 to 80 A), making it suited for resistive or lighting loads where inrush is low — not for motor starting or transformer primary circuits that need a C or D curve.
Mounts on DIN rail (REG) in any position. Occupies 1 modular width unit (18 mm wide). Depth is 68.5 mm, installation depth 70 mm. IP20 with connected protective device and conductors — intended for enclosed distribution boards, not wet or dusty environments. Halogen-free and silicon-free construction, rated for ambient temperatures from -40 °C to 75 °C (55 °C at 95% RH). Mechanical service life 10,000 operating cycles typical.
