The Schneider Electric CR1F1504F7 is a TeSys F bistable magnetic contactor — a 4-pole (4 NO) device rated for 150 A in AC-1 duty (resistive loads) at 440 V, with a conventional free-air thermal current (Ith) of 250 A at 40 °C. The coil is 110 V, accepting both AC (50/60 Hz and 400 Hz) and DC control voltages. Bistable means the contactor latches and unlatches via a pulse on the coil, holding its state without continuous coil power — useful for energy-saving or UPS-backed circuits where sustained coil draw is undesirable.
The 150 A AC-1 rating is the continuous resistive current the main poles can carry. The 4-pole configuration (all NO) means it switches four independent circuits simultaneously, common for three-phase plus neutral or dual-load applications. Control voltage limits are 0.85 to 1.1 Uc for both latching and unlatching, so the 110 V coil will reliably operate between roughly 93.5 V and 121 V. Operating time is 35 to 40 ms to latch and 50 to 100 ms to unlatch — fast enough for most panel switching but not for high-speed inverter pre-charge circuits.
Physical dimensions are 301 mm high, 201.5 mm wide, and 171 mm deep — a substantial footprint that needs a clear DIN-rail or backplate area in the enclosure. Power terminals use bolted connections, so plan for wrench access and torque tooling. The TH protective treatment indicates a tropicalized coating for humid or corrosive environments. Operating altitude is 3000 m without derating, and ambient temperature range is -15 to 70 °C, covering most indoor industrial panel conditions.
