Combines thermal (overloads) and magnetic (short-circuits) protection thanks to the C curve, which trips between 5× and 10× the rated current. This makes it suitable for resistive (lighting, outlets) and inductive (motors, air conditioners) loads.
Designed for 230 Vac systems and 50-60 Hz frequency, with impulse voltage Uimp = 4 kV and rated breaking capacity Icn = 4.5 kA. Limitation class 3, minimizes short-circuit effects.
With only 2 DIN modules (36 mm width) and dimensions 81×36×78 mm, it is designed for small but complete modular switchboards. Easy mounting on 35 mm DIN rail, ideal for residential installations or subpanels.
Low power dissipation 6 W, facilitates insertion into compact panels with low heat loss while maintaining high performance.
Compatible with auxiliary contact (AX-X1), alarm contact (AL-X1), trip coils (SHT-X1) and minimum voltage coils (UVT-X1). Cannot be combined with differential modules.
