Part Identification and Function
The CR1F1504G7 is a TeSys F magnetic latching contactor from Schneider Electric, configured as a 4-pole device with 4 normally open power poles. It is designed for motor control and resistive load switching, rated for utilisation categories AC-1, AC-3, and AC-4. Rated operational current is 150 A under AC-4 duty at ≤ 440 V (40 °C), with a higher 250 A rating under AC-1 for resistive loads. This means the contactor is sized for heavy-duty motor starting and reversing applications where AC-4 ratings govern the switching of inrush currents.
Motor power capability spans 40 kW at 220–230 V AC up to 100 kW at 690 V AC (50/60 Hz). Under UL/CSA ratings, it handles 125 hp at 575–600 V for three-phase motors. These figures define the maximum motor frame size this contactor can switch across common global voltage standards. Rated breaking capacity is 1500 A at 220–440 V for the power circuit, reducing to 450 A at 1000 V. This ensures the contactor can interrupt fault currents within its rated voltage range without welding or excessive arcing — critical for coordination with upstream protective devices. The control circuit operates on 127 V AC (50–400 Hz) or 127 V DC, with latching and unlatching voltage limits of 0.85–1.1 Uc. Average consumption is 1260 VA during latching and 10 VA during unlatching — the high inrush for the latching pulse must be factored into control transformer sizing. This suits applications with moderate cycling demands — not continuous high-speed pick-and-drop operations.
The CR1F1504G7 is certified to IEC 60947-4, BS 5424, VDE 0660, JEM 1038, and NF C 63-110. Rated insulation voltage is 1000 V per IEC 60947-4 and IEC 60158-1, with a VDE 0110 group C rating of 1500 V. These certifications confirm the contactor meets international standards for low-voltage switchgear and motor control. The TH protective treatment indicates suitability for tropical environments with humidity and condensation.
Dimensions are 6.7 in (171 mm) depth, 7.9 in (201.5 mm) width, and 6.7 in (170 mm) height — a compact footprint for a 150 A rated contactor, but panel layout must account for the 201.5 mm width across four pole connections. Power circuit connections accept lugs, ring terminals, bars (up to 2 x 25 x 3 mm), or connectors up to 120 mm². Tightening torque is 159.3 lbf·in (18 N·m) — a calibrated torque wrench is required for termination to avoid high-resistance joints. Associated fuse rating is 160 A aM or gG at ≤ 440 V for the power circuit, or 250 A BS88. This guides the selection of upstream short-circuit protection for type 2 coordination.
As a magnetic latching contactor, it maintains its switched state without continuous coil power — relevant for applications where coil power savings or hold-in current reduction is required. This is a distinct subset within the TeSys F family; verify that the latching function is required for your control scheme before specifying.
