The CR1F2654N7 is a TeSys F magnetic latching contactor from Schneider Electric — a 4-pole, 4 NO device rated for 265 A operational current at ≤ 440 V AC in AC-3 duty, and 350 A in AC-1. That latching feature is the key differentiator: once pulsed, it stays closed magnetically, so it doesn't drain control power or generate heat in the coil circuit during normal running.
The headline 265 A isn't the full story — that's the rated operational current (Ie) in AC-3 (motor switching) at ≤ 440 V, 40 °C. In AC-1 (resistive loads), it carries 350 A. So if you're driving a motor, size on the 265 A figure; if it's a heater bank, you get more headroom. The motor power table covers the voltage sweep: 132 kW at 380-400 V, 160 kW at 690 V, and 175 hp under UL/CSA at 575-600 V. The latching coil pulls 1800 VA on the pulse but only 12 VA to unlatch — that's the spec to check against your control transformer sizing. Breaking capacity is 2450 A at 440 V for the power circuit, which is well above typical fault levels in a motor branch circuit, but you still need the upstream fuse or breaker for SCCR coordination.
Integration notes
Panel mounting is straightforward: the contactor bolts to a panel or clips onto a notched AM1-EC rail. The power terminals accept lugs, ring terminals, or bars up to 240 mm² — torque to 35 N·m (309.8 lbf·in). The 4 NO power poles are all normally open, so plan your control scheme accordingly; there are no built-in auxiliary contacts, so you'll need a separate auxiliary block if you need feedback for a PLC or status indication.
