Overview
The CR1F400F7 is a Schneider TeSys F reversing magnetic latching contactor, order code CR1F400F7, rated for 400 A switching current at up to 1000 V insulation voltage with a 110 V AC/DC control coil. This 3-pole unit carries a 4 kA breaking capacity and is designed for horizontal or vertical mounting, suiting high-current reversing motor and power switching applications.
As a magnetic latching contactor, the CR1F400F7 uses a pulsed coil to switch and hold the main contacts without continuous power draw — the coil consumes 1600 VA during the latching pulse and only 16 VA to unlatch, reducing heat and energy in sustained closed states. The 400 A rated switching current (AC-1/AC-3/AC-4 utilization categories) and 4500 A making capacity handle heavy motor starts and resistive loads; the 4 kA breaking capacity covers fault clearing with associated fusing rated at 400 A aM or 500 A gG. Average impedance of 0.28 mOhm at 500 A 50 Hz keeps voltage drop low, while the 40 ms operating time supports fast reversing sequences.
Applications
Reversing contactors of this class are used in motor control centres, conveyor drives, hoists, and pump stations where forward/reverse direction switching is required under load. The magnetic latching feature suits applications needing a held closed state without continuous coil power, such as emergency stop circuits or energy-conscious installations.
Within Schneider's TeSys F range, the CR1F400F7 occupies the high-current reversing contactor segment, specified by panel builders and OEMs for 400 A class motor circuits and power distribution where reversing functionality is integral. Its magnetic latching design distinguishes it from standard contactors in applications requiring low standby power or fail-safe hold.
The CR1F400F7 carries certifications under CB Scheme, UL, CSA, EAC, CE, and UKCA, and complies with EN/IEC 60947-1, EN/IEC 60947-4-1, JIS C8201-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1.
