The Schneider Electric A9N16206 is a 2-pole residual current circuit breaker (RCCB) from the Acti9 xID series, rated 40 A at 230-240 V AC, 50 Hz. The 300 mA sensitivity is suited for equipment protection or fire prevention, not direct personal shock protection.
Clip-on mounting to a standard 35 mm DIN rail, 2-pole wide (36 mm, occupying 4 modular pitches of 9 mm). The neutral is on the left. The 18 mm phase-to-phase pitch keeps busbar compatibility with the Acti9 range. IP20 rated — intended for enclosed distribution boards, not washdown or outdoor exposure. The toggle provides local indication of ON, OFF, and fault-trip states, plus a padlocking provision for lockout/tagout during panel maintenance.
