The Schneider Electric CR1F5004Q7 is a TeSys F magnetic latching contactor — a 4-pole, normally open device rated for 500 A operational current (AC-3 duty) at up to 1000 V AC. It's built for motor control and resistive loads, covering utilisation categories AC-1, AC-3, and AC-4. The latching coil holds position without continuous power, drawing 1800 VA on latch and 13 VA on unlatch, with a control circuit voltage of 380 V AC 50/60 Hz. Motor power ratings span from 147 kW at 220...230 V AC up to 335 kW at 690 V AC and 1000 V AC (50/60 Hz). For UL/CSA installations, it's rated at 500 hp at 575...600 V AC for three-phase motors. That kind of power handling puts it squarely in heavy industrial gear — think large pumps, compressors, conveyors, or any motor load that needs a positive latching contactor to stay closed without coil power.
AC-3 (squirrel-cage motor starting) and AC-4 (plugging, inching) demand higher making and breaking capacities than AC-1 (resistive). The mechanical durability of 1 million cycles (Mcycles) and a maximum operating rate of 120 cycles per hour at 40 °C give a clear duty-cycle limit for high-repetition applications. The contactor mounts on a notched AM1-EC rail, and the terminals accept lugs or ring terminals up to 240 mm² or bars up to 40 x 5 mm. Tightening torque is 35 N.m — substantial, so plan for a torque wrench during installation. The IP20 front face protection means it's suitable for enclosed panels, not open washdown areas.
The contactor meets IEC 60947-4, BS 5424, VDE 0660, NF C 63-110, and JEM 1038. Rated insulation voltage is 1000 V per IEC 60947-4 and 1500 V per VDE 0110 Group C.
At 9.1 in deep, 11.3 in wide, and 9.4 in tall, this is a large-frame contactor — plan for panel depth and side clearance for cable bending radius. It's designed for the notched AM1-EC rail, which is a heavy-duty DIN-style mounting profile. The power dissipation per pole is 45 W in AC-3 and 88 W in AC-1, so heat buildup inside the enclosure needs to be factored into the cooling design. The associated fuse rating for the power circuit is 500 A aM or 800 A gG at up to 440 V — a key coordination point for selectivity studies. Operating altitude is 3000 m without derating, and the ambient temperature range is -15 °C to 70 °C. Storage range is wider at -60 °C to 80 °C, which covers most shipping and warehouse conditions.
