The CR1F500FZ7 is a TeSys F magnetic latching contactor from Schneider Electric — 3-pole, rated for 500 A operational current (AC-3 duty) and a 110 V DC low-consumption latching coil. It's built for motor control and resistive loads across AC-1, AC-3, and AC-4 utilization categories. The latching mechanism holds the main contacts closed with a 550 W DC pulse and unlatches at 60 W DC, meaning the coil only draws power during the switching event — no continuous hold-in power, which matters for applications where coil heating or energy efficiency is a concern.
The motor power table backs that up: 335 kW at 690 V, 280 kW at 415 V, 250 kW at 380–400 V. For UL/CSA installations, the horsepower ratings are 500 hp at 575–600 V and 400 hp at 460–480 V. The 110 V DC low-consumption coil has a latching voltage tolerance of 0.85–1.1 Uc, so it picks up reliably down to about 93.5 V DC and drops out at the same threshold. The unlatching coil draws 60 W DC — a separate pulse to release the latch. This dual-coil latching design is common in applications where a momentary power loss must not drop the load (e.g., conveyor hold, crane brakes).
This is a frame-style contactor — 232 mm deep, 233 mm wide, 238 mm high — sized for bolted busbar connections. The terminals accept lugs or ring terminals on up to 2 cables of 240 mm² each, or busbars up to 40 x 5 mm. Tightening torque is 35 N·m, so a torque wrench is expected during installation. The TH protective treatment (tropicalization) means it's coated for humid or mildly corrosive environments, but it's not rated for washdown — no IP rating is listed, so it belongs in a ventilated enclosure, not on the open floor.
The contactor carries a rated insulation voltage (Ui) of 1000 V conforming to IEC 60158-1, IEC 60947-4, and BS 775, plus 1500 V conforming to VDE 0110 group C. These are the core electrical safety certifications for industrial control gear — they confirm the part meets IEC/EN 60947-4-1 for contactors and motor starters. No UL/CSA listing number is explicitly stated in the spec record, but the horsepower ratings for UL/CSA imply UL recognition or CSA certification for the North American market. RoHS and REACH compliance is standard for Schneider's TeSys range, though not explicitly cited in this ledger.
