Rated operational current is 185 A in AC-4 duty at ≤440 V (the category for plugging and inching of motors) and 275 A conventional free-air thermal current (Ith) at 104 °F (40 °C). The 110 V DC low-consumption control circuit operates within 0.85 to 1.1 Uc for both latching and unlatching. The AC-3 motor-switching capability is what most buyers will size against: 100 kW at 440 V AC, 110 kW at 690 V AC, 90 kW at 380...400 V AC, and 55 kW at 220...230 V AC. For UL/CSA installations, the horsepower ratings are 150 hp at 575...600 V, 125 hp at 460...480 V, 60 hp at 220...240 V, and 50 hp at 200...208 V, all for 3-phase motors. Rated breaking capacity is 1800 A at 220...440 V, 1600 A at 500 V, 1200 A at 660/690 V, and 600 A at 1000 V, which tells you it can interrupt locked-rotor currents at those voltages. The rated short-time withstand current (Icw) is 1500 A for 1, 5, and 10 seconds at 104 °F (40 °C), tapering to 400 A for 10 minutes — this matters for coordination with upstream protective devices during a fault. This is a panel-mounted contactor sized for motor control centers and industrial control panels. Dimensions are 7.1 in (181 mm) deep, 8.2 in (208.5 mm) wide, and 6.9 in (174 mm) high — a substantial footprint that needs clear access for the bar and lug-ring terminal connections. Terminals accept bars (2 x 25 x 3 mm), lug-ring terminals, and connectors up to 150 mm² (0.2 in²). Tightening torque is 159.3 lbf·in (18 N·m) on the power connections. Operating altitude is 9842.52 ft (3000 m) without derating, so it works at most high-altitude plant sites without a current reduction. Ambient operating temperature range is 5...158 °F (-15...70 °C), with storage from -76...176 °F (-60...80 °C). The protective treatment is TH (tropicalised/humid environment), which means it has conformal coating for corrosion resistance in damp conditions. ## What the approvals and standards tell you Rated insulation voltage (Ui) is 1000 V per IEC 60158-1 and IEC 60947-4, 1000 V per BS 775, and 1500 V per VDE 0110 group C. Rated impulse withstand voltage (Uimp) is 8 kV. These figures confirm the contactor is designed for 1000 V AC systems with adequate clearance and creepage for industrial environments. The associated fuse ratings are 200 A aM, 315 A BS88, and 315 A gG at ≤440 V — use these for short-circuit coordination. The average impedance is 0.36 mOhm at Ith 275 A, 50 Hz, which gives a power dissipation per pole of 12 W in AC-3 and 26 W in AC-1 — factor this into panel thermal calculations if running near the thermal limit.","metaTitle":"CR1F1854FZ7 TeSys F Magnetic Latching Contactor, 185 A AC-4,","metaDescription":"CR1F1854FZ7 TeSys F magnetic latching contactor. 4-pole, 185 A rated operational current (AC-4) at ≤440 V. 110 V DC low-consumption coil.
