As a magnetic latching contactor, the CR1F150U7 uses a pulse on the 240 V AC coil to change state and holds that position without continuous coil power — the latching mechanism reduces heat dissipation and standby consumption. The coil draws 1100 VA during the latching pulse and 7.3 VA during unlatching, with an average impedance of 0.45 mOhm at 250 A 50 Hz. The rated making capacity of 1700 A (Irms) defines the peak inrush the contacts can close onto without welding — critical for motor starting or capacitor bank switching. The breaking capacity (Icu) is 1.5 kA, suitable for typical motor branch circuits with upstream fuse protection; the recommended associated fuse rating is 160 A aM or 250 A gG at ≤ 440 V. The contactor is rated for utilization categories AC-1 (resistive), AC-3 (squirrel-cage motor starting), and AC-4 (plugging/inching), covering the majority of industrial motor and resistive load applications.
The CR1F150U7 is an active Schneider TeSys F catalog item. It carries product certifications under CB Scheme, UL, CSA, EAC, CE, and UKCA, and is manufactured to EN/IEC 60947-1 and EN/IEC 60947-4-1 standards. Sourcing is via standard distributor channels; lead times and minimum order quantities are confirmed at quote.
