The Schneider Electric A9N19816 is a miniature circuit breaker from the Acti9 C120H range, rated 100 A at 30 °C, single-pole, with a C curve and a breaking capacity of 10 kA Icn/Icu at 230 V AC.
The breaker is certified to GB 10963.1, EN/IEC 60898-1, GB/T 14048.2, and EN/IEC 60947-2. The dual standard means it meets both the household (60898-1) and industrial (60947-2) requirements — useful when the same panel must satisfy both a local code and an end-client's specification. The 6 kV impulse withstand voltage (Uimp) and 500 V rated insulation voltage (Ui) confirm it handles typical transient overvoltages in a 230/400 V network.
Panel integration
Tunnel terminals accept up to 50 mm² rigid or 35 mm² flexible cable. The toggle provides local ON/OFF indication and a contact-position indicator confirms the state for isolation — the breaker is marked suitable for isolation per the standards.
