The CR1F4004M7 is a Schneider Electric TeSys F magnetic latching contactor — 4 poles, all normally open (4 NO), rated for 400 A operational current in AC-4 duty and 500 A in AC-1 at ≤ 440 V. The coil accepts 220-230 V AC (50-400 Hz) or DC, with latching consumption of 1600 VA and unlatching consumption of 16 VA.
The 400 A AC-4 rating governs switching of severe-duty motor loads (e.g., reversing, plugging) — this is the rating that matters for a motor control application, not the higher AC-1 resistive figure. The 500 A AC-1 rating covers resistive heating or lighting loads. The 4 NO pole configuration means all four poles switch line power; there are no auxiliary contacts built in. The 220-230 V AC/DC coil voltage is not dual-frequency auto-sensing — verify supply matches. The latching mechanism holds the main contacts closed without continuous coil power, reducing heat and energy consumption in applications where the contactor stays closed for long periods.
This part is classified as obsolete by the manufacturer. Confirm fit by reviewing the 400 A AC-4 rating, 4 NO pole count, and 220-230 V AC/DC coil voltage against your BOM line. If you are evaluating a replacement, compare the physical dimensions (219 mm depth, 261 mm width, 206 mm height) and bolted power connections (lugs/ring terminals up to 150 mm², bars 30 x 5 mm) to ensure panel fit.
Electrical performance and protection
The rated breaking capacity ranges from 4000 A at 220-440 V down to 1200 A at 1000 V, with a making capacity of 4500 A (Irms). Short-time withstand current (Icw) is 3600 A for 1 s at 40 °C, derating to 1000 A for 10 min — useful for coordination studies. The manufacturer recommends associated fusing of 400 A aM or 500 A gG at ≤ 440 V. The coil consumption and control voltage limits (0.85-1.1 Uc for both latching and unlatching) should be checked against your control transformer sizing.
