The CR1F265EZ7 is a TeSys F magnetic latching contactor — 3 poles, 3 normally open, rated for 265 A in AC-4 duty at 40 °C. That AC-4 rating (plugging/inching of motors) is the demanding one; AC-1 resistive load capability is higher at 350 A. The 48 V DC coil is a low-consumption latching type: it pulls 500 W to latch, then holds magnetically with no continuous coil power, which matters for control panels where heat buildup or UPS-backed DC supplies are a concern. Rated insulation voltage is 1000 V per IEC 60947-4 and BS 775, with a 1500 V rating per VDE 0110 group C. That puts it squarely in 690 V and 1000 V AC line-up applications where phase-to-phase clearance is tight. The rated operational voltage covers 25 to 200 Hz AC up to 1000 V, so it handles both standard 50/60 Hz and higher-frequency supplies like those from VFD output filters. Breaking capacity is 2450 A at 220–440 V, tapering to 800 A at 1000 V. Short-time withstand current is 2200 A for up to 10 seconds — enough to coordinate with upstream 315 A aM or 400 A gG fuses without the contactor welding shut during a fault. The 2940 A making capacity confirms it can close onto a short-circuit without contact damage.
This is a panel-mount contactor, not DIN-rail snap-on. The 213 mm depth, 201.5 mm width, and 203 mm height mean it needs a backplate or chassis mount with clearance for the 35 N.m lug torque. Connections accept lugs or ring terminals up to 240 mm², plus bars up to 32 x 4 mm — sized for the 265 A continuous path without an external terminal block. Operating temperature range is -15 to 70 °C, storage -60 to 80 °C. The 3000 m altitude rating without derating covers most installations outside high-mountain or pressurized environments. Maximum operating rate is 120 cycles per hour at 40 °C — fine for motor starting duty, not for high-speed jogging applications.
