The coil holds on 220 VDC and draws 500 W during latching, then drops to 20 W holding. This latching design means the main contacts stay closed without continuous coil power, which saves energy and reduces heat in the panel. Rated operational current (Ie) is 185 A at ≤440 V AC in AC-3, which covers standard squirrel-cage motor starting and running. The conventional free-air thermal current (Ith) is 275 A at 40 °C — this is the resistive-load limit for continuous duty. Motor power capability runs from 55 kW at 220–230 V up to 110 kW at 690 V AC, so it fits medium-voltage motor circuits across common global supply voltages. Rated insulation voltage (Ui) is 1000 V per IEC 60947-4 and BS 775, with impulse withstand (Uimp) at 8 kV. The rated breaking capacity is 1800 A at 440 V, which handles fault clearing under most motor-start conditions. Short-time withstand (Icw) holds 1500 A for 10 seconds — enough to coordinate with upstream fuses or breakers during a fault hold-off. Associated fuse sizing recommends 200 A aM or 315 A gG at ≤440 V, so match the branch-circuit protection to these values for selectivity. The contactor measures 7.1 in deep, 8.2 in wide, 6.9 in tall — a substantial footprint for a 185 A class. Terminals accept bars (2 x 25 x 3 mm), ring lugs, or connectors up to 150 mm². Tightening torque is 159.3 lbf·in (18 N·m), so use a torque wrench on the main power connections. Mounting is screw-fixed to a backplate; it's not a DIN-rail snap-on, so plan for direct panel mounting. Altitude rating is 3000 m without derating — fine for most plant-floor installations. The TH protective treatment indicates tropicalization for humidity and corrosion resistance, relevant in washdown or coastal environments.","metaTitle":"TeSys F CR1F1854MZ7 Magnetic Latching Contactor, 185 A, 220","metaDescription":"Schneider TeSys F CR1F1854MZ7 magnetic latching contactor, 4-pole NO, 185 A rated current, 220 VDC coil.
