The Schneider CR1F5004GZ7 is a TeSys F magnetic latching contactor — 4 poles, rated 700 A conventional free air thermal current (Ith) at 40 °C, with a 127 V DC low-consumption coil. Latching means the main contacts hold position without continuous coil power; the coil draws 550 W to latch and 60 W to unlatch, with a typical operating time of 40 to 80 ms latching and 50 to 100 ms unlatching. This is a control-duty contactor (utilisation categories AC-1, AC-3, AC-4) suited for motor control and resistive loads. The 700 A Ith rating means the contactor can carry that current continuously in free air at 40 °C without exceeding its thermal limits. For motor applications, the key figure is the AC-3 rated operational current: 500 A at ≤ 440 V, 460 A at < 40 °C. That translates to motor power ratings across common voltages — 335 kW at 690 V AC, 295 kW at 440 V, 280 kW at 415 V, 250 kW at 380 to 400 V, and 147 kW at 220 to 230 V (all 50/60 Hz). Under UL/CSA, it's rated 500 hp at 575 to 600 V, 400 hp at 460 to 480 V, and 200 hp at 220 to 240 V.
Rated operational voltage is 1000 V AC at 25 to 200 Hz, with a rated insulation voltage of 1000 V (conforming to IEC 60158-1, IEC 60947-4, BS 775) and 1500 V per VDE 0110 group C. Impulse withstand voltage is 8 kV — this tells you the contactor can handle transient overvoltages common in industrial power distribution without flashover. The rated short-time withstand current (Icw) is 4200 A for 1, 5, or 10 seconds at 40 °C, stepping down to 3200 A at 30 s, 2400 A at 1 min, 1500 A at 3 min, and 1200 A at 10 min. That's the current the contactor can carry momentarily during a fault without welding or damage, critical for coordination with upstream protective devices. Rated breaking capacity is 5000 A at 220 to 440 V, 4500 A at 500 V, 3560 A at 660/690 V, and 2500 A at 1000 V. Rated making capacity is 5000 A. These numbers define the maximum fault current the contactor can safely interrupt or close into — essential for verifying selectivity in a motor control centre. Associated fuse ratings are 500 A aM, 800 A BS88, and 800 A gG at ≤ 440 V, giving a clear guide for coordination. Average impedance is 0.18 mOhm at 700 A, 50 Hz. Power dissipation per pole is 45 W in AC-3 duty and 88 W in AC-1 — relevant for panel thermal budgeting, especially in enclosed assemblies.
This is a large-frame contactor — 288 mm wide, 238 mm high, 232 mm deep. It's not a DIN-rail snap-on; it bolts into a panel or enclosure. Terminals accept lugs or ring terminals for up to two 240 mm² cables per pole, or bars with a busbar cross-section of 40 x 5 mm. Tightening torque is 35 N.m. The contactor has 4 NO power poles (no built-in auxiliary contacts in this variant). Protective treatment is TH (tropicalised, humidity-resistant). The control circuit voltage limits are 0.85 to 1.1 Uc for both latching and unlatching — meaning the 127 V DC coil holds in reliably from about 108 V to 140 V DC.
