The CR1F150N7 is a TeSys F bistable magnetic contactor from Schneider Electric, configured as a 3-pole normally open device with a 415 V AC 50/60 Hz control coil. Bistable means the contactor latches magnetically and holds without continuous coil power — the coil draws 1100 VA during the 35...40 ms latching pulse, then drops to 7.3 VA for the unlatching pulse (50...100 ms). This makes it suitable for applications where holding power must be minimized or where a sustained coil signal is unreliable. Its headline rating is 150 A at 440 V in AC-3 duty (motor switching), with a conventional free-air thermal current Ith of 250 A at 40 °C. The AC-3 rating governs motor starting and running; the AC-1 rating (resistive loads) and AC-4 rating (plugging/inching) are also declared. For a 150 A AC-3 contactor, the power dissipation per pole runs 6 W in AC-3, 18 W in AC-1, and 25 W in AC-4 — so panel thermal design should account for the duty cycle.
Rated breaking capacity varies with voltage: 1500 A at 220...440 V, 1200 A at 500 V, 1100 A at 600...690 V, and 450 A at 1000 V for the power circuit. Making capacity is 1700 A rms. Associated fuse recommendations are 160 A aM, 250 A gG, or 250 A BS88 for the power circuit — these guide the upstream short-circuit protection selection for Type 1 or Type 2 coordination.
The contactor uses bolted connections and is rated for operation from -15 to 70 °C ambient, with no derating required up to 3000 m altitude. Operating position tolerance is ±5°. Mechanical durability is rated at 1,000,000 cycles, and the maximum operating rate is 120 cycles per minute at 40 °C. Protective treatment is TH (tropicalized). Dimensions are 301 mm high, 163.5 mm wide, 171 mm deep — a substantial footprint for panel layout planning.
