The CR1F1504M7 is a TeSys F magnetic latching contactor from Schneider Electric, configured with 4 normally open power poles and rated for 250 A at 250 A (AC-1) and 150 A (AC-3) at <= 440 V. The coil is rated for 220...230 V AC 50...400 Hz or 220...230 V DC, with a latching consumption of 1260 VA (AC) or 1260 W (DC). This is a 4-pole device designed for resistive load and motor control applications (AC-1, AC-3, AC-4 utilization categories).
The 250 A rating in AC-1 (resistive load) sets the maximum continuous current for non-inductive loads like heaters or lighting. The 150 A AC-3 rating (motor starting/switching) is the one that governs motor control applications — it reflects the contactor's ability to handle inrush currents during motor starts. The mechanical durability of 1 Mcycles gives a baseline for expected service life in high-cycle applications.
This contactor uses bolted power circuit connections accepting lugs, ring terminals, or bars up to 120 mm². The tightening torque is 159.3 lbf.in (18 N.m). The control circuit operates on AC 50...400 Hz or DC standard. Operating altitude is rated to 9842.52 ft (3000 m) without derating. The device is part of the TeSys F range, designed for panel integration with standard mounting.
