The Schneider CR1F400EZ7 is a TeSys F bistable magnetic contactor — three power poles, normally open, rated for heavy motor and resistive loads. The coil is 48 VDC, low-consumption type: 500 W to latch, 70 W to unlatch, with operating times of 40–75 ms latching and 50–100 ms unlatching. The part ships as a set of 10 units.
The utilisation categories tell you the load type: AC-3 for squirrel-cage motors (starting and stopping under load), AC-1 for resistive heating or lighting. The rated breaking capacity varies by voltage — 4000 A at 220–440 V, 3500 A at 500 V, 3000 A at 600–690 V, and 1200 A at 1000 V — so it clears faults up to those levels without welding. Power dissipation per pole is 45 W in AC-3 and 70 W in AC-1 — factor that into panel heat calculations. Mechanical durability is 1 million cycles; maximum operating rate is 120 cycles per minute at 40 °C. The control circuit insulation is rated 1000 V per IEC 60947-4 and BS 775, with 1500 V per VDE 0110 group C.
Dimensions are 375 mm high, 261 mm wide, 219 mm deep — a large-frame contactor sized for panel mounting, not DIN-rail snap-on. Operating position tolerance is ±5° from vertical. Ambient temperature range is -15 to 70 °C. Protective treatment is TH (tropicalised, for humid environments). The associated fuse ratings for the power circuit are 400 A aM, 500 A BS88, or 500 A gG — match the fuse type to your coordination study.
