The coil accepts 110 V AC (50/60 Hz or 400 Hz) or 110 V DC, and the bistable (latching) design holds its state without continuous coil power, reducing heat and energy draw in applications where the contactor stays closed for long periods. Rated operational current (Ie) is 185 A in AC-3 (motor switching) and 275 A in AC-1 (resistive) at <40 °C, with a conventional free-air thermal current (Ith) of 250 A at 40 °C. The utilisation categories cover AC-1, AC-3, and AC-4 — so it's rated for both normal motor start/stop and plugging/reversing duty. Breaking capacity reaches 1200 A at 660/690 V, 1600 A at 500 V, and 1800 A at 220–440 V, giving solid fault-clearing headroom for a motor branch circuit. ## Coil and control circuit details Control voltage is 110 V AC/DC, with latching and unlatching limits of 0.85–1.1 Uc. Operating time is 35–40 ms for latching and 50–100 ms for unlatching. Average consumption peaks at 1750 VA (AC 400 Hz or DC) during latching, dropping to 8–11 VA for unlatching — the inrush is brief but significant, so the control transformer or DC supply must be sized for that surge. The control circuit insulation is rated 1000 V per IEC 60947-4 and VDE 0110 Group C. ## Physical integration and environment Dimensions are 305 mm high, 208.5 mm wide, and 181 mm deep — a substantial footprint for a 4-pole contactor at this current level. Bolted connections (not spring-cage) mean the installer needs ring-tongue or fork terminals and a torque wrench for the power circuit. Ambient temperature range is –15 to 70 °C.","metaTitle":"Schneider CR1F1854F7 TeSys F Bistable Contactor, 4P, 185A AC","metaDescription":"Active-production Schneider CR1F1854F7 bistable contactor, 4 poles, 185 A AC-3 at 440 V, coil 110 V AC/DC.
