It's a control contactor for resistive and motor loads, built for panel applications where the contactor must hold its state without continuous coil power. The latching coil draws 1450 VA at 50/60 Hz to pull in, then the unlatching coil (24 V DC) draws 16 W to release; between those events, the contacts stay closed magnetically with zero coil dissipation. The 400 A rating in AC-3 (motor switching) means this contactor handles induction motors up to 200 kW at 380–400 V, 220 kW at 415 V, and 250 kW at 440 V. For AC-1 resistive loads, the Ith of 500 A is the limit. That 8 kV impulse rating means it survives transient overvoltages common in industrial distribution without flashover — important for panels fed by long cable runs or near VFDs. Short-time withstand current (Icw) is 3600 A for 1 second at 40 °C, dropping to 1000 A for 10 minutes. Rated breaking capacity reaches 4000 A at 220–440 V, and making capacity is 4500 A — both well above the Icw, confirming the contactor can close into and interrupt fault currents within its rating. This is a lug-ring terminal contactor accepting two 150 mm² cables per pole, or busbars up to 30 × 5 mm. Tightening torque is 35 N·m — substantial, so budget for a torque wrench on the install. Dimensions are 213 mm wide, 206 mm high, 219 mm deep. It's a panel-mount device, not DIN-rail; plan for bolt-down mounting and adequate clearance for cable bending radius. The TH protective treatment means it's tropicalized for humid environments.","metaTitle":"Schneider CR1F400MB7 TeSys F Magnetic Latching Contactor, 40","metaDescription":"Schneider TeSys F CR1F400MB7 magnetic latching contactor, 3P, 400 A rated operational current, 220 V/24 V AC/DC coil.

UL/CSA motor power ratings are listed for 200–600 V three-phase motors.

The same frame size is shared with other coil voltage variants (e.g., 24 V AC latching, 110 V DC latching) and with the standard electrically-held CR1F400 contactors. The physical footprint and terminal arrangement are identical across the 400 A TeSys F line, so swapping coil voltages requires no panel rework."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/CR1F400MB7","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/CR1F400MB7 when reusing this data.
