Its 110 V DC low-consumption coil latches magnetically, meaning it holds position without continuous coil power, drawing 500 W DC during latching and 40 W DC during unlatching. This makes it suited for applications where sustained coil energisation is undesirable or where power must be conserved. The headline rating is 265 A in AC-4 duty at ≤440 V (40 °C ambient), which governs switching of motors under starting and plugging conditions — the most demanding utilisation category for contactors. For AC-3 (normal motor start/run) the same contactor carries 350 A, and for AC-1 (resistive loads) it also carries 350 A. Motor power ratings span the voltage range: 132 kW at 380-400 V AC, 140 kW at 415 V, 160 kW at 500-660 V, and 147 kW at 1000 V AC (all 50/60 Hz). UL/CSA horsepower ratings are also provided: 150 hp at 460-480 V, 175 hp at 575-600 V. The rated operational voltage (Ue) is 1000 V AC at 25-200 Hz, with a rated insulation voltage (Ui) of 1000 V per IEC 60947-4 and IEC 60158-1.
The rated breaking capacity tells you the fault-clearing ability: 2450 A at 220-440 V, 2200 A at 500 V, 1700 A at 660/690 V, and 800 A at 1000 V. The rated making capacity (Irms) is 2940 A — the peak inrush the contactor can close onto. These numbers matter for coordination with upstream protection: the associated fuse ratings are 315 A aM, 400 A BS88, or 400 A gG at ≤440 V. Short-time withstand (Icw) is 2200 A for 1, 5, and 10 seconds, then derates to 1230 A at 30 s, 950 A at 1 min, and 480 A at 10 min. This defines how long the contactor can carry fault current without welding closed — critical for selective coordination studies. Operating time is 50-100 ms unlatching and 45-50 ms latching. The control circuit voltage limits are 0.85 to 1.1 Uc for both latching and unlatching, so the 110 V DC coil will operate reliably between roughly 93.5 V and 121 V DC. Average impedance per pole is 0.32 mOhm at 350 A, 50 Hz, which translates to power dissipation of 22 W per pole in AC-3 and 39 W per pole in AC-1.
The CR1F2654FZ7 is a panel-mount contactor — not DIN-rail snap-on. Dimensions are 8.4 in (213 mm) deep, 9.6 in (244.5 mm) wide, and 8.0 in (203 mm) tall. Connections accept lugs, ring terminals, or bars: one 240 mm² connector per pole, or two 32 x 4 mm bars. Tightening torque is 35 N.m (309.8 lbf.in) on the main power terminals. The protective treatment is TH (tropicalised), suitable for humid or corrosive environments. The contactor is rated for control applications and carries utilisation categories AC-1, AC-3, and AC-4 — covering resistive heating, standard motor starting, and severe motor duty (plugging, inching).
