The CR1F2654MZ7 is a TeSys F magnetic latching contactor from Schneider Electric, designed for control applications where the coil must hold its state without continuous power. The 265 A rated operational current in AC-4 duty (at ≤104 °F / 40 °C, ≤440 V AC) is the figure that governs motor reversing, inching, or plugging applications — the most severe switching category for a contactor, where it makes and breaks stalled-rotor currents. For less demanding AC-3 motor starting, the same pole set carries 350 A conventionally. The 220 V DC low-consumption control circuit draws 500 W during latching and 40 W during unlatching, meaning the coil power supply must be sized for the inrush, not the hold. The 4-pole configuration (4 NO) suits three-phase motor circuits with a spare pole for auxiliary switching or a second load. The 1 Mcycles mechanical durability rating sets the expected life before a mechanical rebuild — at 120 cycles per hour maximum operating rate, that is roughly 8,333 hours of continuous cycling at full rate. The 8 kV rated impulse withstand voltage (Uimp) and 1000 V rated insulation voltage (Ui) per IEC 60947-4 mean the contactor is coordinated for 400 V and 690 V distribution systems with adequate clearance for surge events.
Integration notes
Mounting dimensions: 8.4 in (213 mm) depth, 9.6 in (244.5 mm) width, 8.0 in (203 mm) height. The lugs-ring terminals accept up to 240 mm² conductor per pole, with two 32 x 4 mm bars as an alternative. Tightening torque is 309.8 lbf·in (35 N·m) — a torque wrench is required for the power connections; hand-tightening will not meet the spec. The associated fuse recommendation is 315 A aM or 400 A gG at ≤440 V, or 400 A BS88 — this coordinates the short-circuit protection with the contactor's 2200 A rated short-time withstand current (Icw) for 1 second.
