Mounts fixed on a DIN rail, 18 mm wide (2 x 9 mm pitches), 81 mm tall, 60 mm deep. Occupies one modular space in an Acti9 distribution board or enclosure. Terminals are tunnel-type, accepting up to 2 x 2.5 mm² flexible or 1 x 2.5 mm² rigid; strip length 9 mm, tighten to 0.8 N·m. IP20 finger-safe per IEC 60529 — suitable for dry indoor panel environments only. ## Electrical ratings and compliance Rated insulation voltage 440 V, overvoltage category III, impulse withstand 4 kV. Control circuit draws 3 VA holding power. Complies with IEC/EN 61095 (electromechanical contactors for household and similar purposes). Ambient operation -5 to 50 °C; storage -40 to 70 °C.","metaTitle":"Schneider Electric A9C18309 Acti9 iACTc Double Control Input","metaDescription":"Schneider Electric A9C18309 Acti9 iACTc double control input auxiliary relay. 24-48 V AC control, 0.2 A holding / 2 A inrush output.
