It occupies 2 modular width units (36 mm) on a DIN rail and is designed for 50 Hz supply systems at 230/240 V AC. The unit is halogen-free and silicon-free, suitable for environments with strict material restrictions.
The breaking capacity is rated 4.5 kA per EN 60898 and 15 kA per IEC 60947-2 — the higher IEC figure applies when the device is used as a distribution board component with upstream current limitation. Energy limitation class 3 means it restricts let-through energy during a fault, helping downstream coordination.
Mounts on a DIN rail in any orientation (mounting position any). The supply can enter from either the top or bottom, simplifying panel wiring.
Thermal derating is specified from 30 °C upward: 10 A at 30 °C, 9.5 A at 40 °C, 9.3 A at 45 °C, 9 A at 50 °C, 8.7 A at 55 °C, 8.5 A at 60 °C, 8.2 A at 65 °C, and 8 A at 70 °C. The test circuit requires a minimum of 100 V for functional testing. Surge voltage withstand is 4 kV, insulation voltage 264 V.
