The Schneider Electric CR1F6304F7 is a TeSys F series magnetic contactor — a bistable (latching) 4-pole device rated for 1000 A in AC-1 duty at 440 V, with a 110 V AC/DC control coil. It switches resistive and motor loads (AC-1 and AC-3 utilisation categories) in heavy industrial panels. The latching coil draws 2100 VA at 50/60 Hz during the latching pulse; unlatching consumption is 8 VA at 50/60 Hz.
The 1000 A AC-1 rating (resistive load) is the headline figure — this contactor is sized for high-current switching in heater banks, power distribution, or large transformer primaries. The AC-3 rating for motor duty is lower (630 A at <40 °C), which governs its use on induction motors. Power dissipation per pole runs 120 W in AC-1 and 48 W in AC-3 — this drives enclosure ventilation requirements. The 1000 A gG or BS88 fuse recommendation for the power circuit sets the upstream protection coordination. The control circuit accepts 110 V AC (50/60 Hz or 400 Hz) or 110 V DC, with a latching voltage tolerance of 0.85...1.1 Uc. The unlatching coil draws only 8 VA at 50/60 Hz — a low holding power after the latching pulse. Operating time is 40...80 ms for latching, 50...100 ms for unlatching.
The CR1F6304F7 is a panel-mount contactor, not DIN-rail snap-on — it bolts into a backplate. Dimensions are 464 mm high by 309 mm wide by 255 mm deep. The TH protective treatment (tropicalisation) suits environments with humidity or condensation. Operating altitude is 3000 m without derating, and the ambient temperature range is -15 to 70 °C. Rated insulation voltage (Ui) is 1000 V for the control circuit per IEC 60947-4 and BS 775, with a 1500 V rating per VDE 0110 group C — confirming its suitability for 690 V line-to-line systems with adequate clearance.
The 4-pole, 1000 A AC-1, 110 V coil configuration is specific — a direct drop-in from current TeSys F production may not exist without a control voltage or pole-count change.
