Schneider Electric TeSys F LC1F185Q7 Contactor, 3P (3 NO), AC-3 185A <=440V, 380V AC Coil

Schneider Electric TeSys F Series LC1F185Q7 Contactor

Manufacturer: Schneider Electric

Product Overview: The Schneider Electric TeSys F LC1F185Q7 is a robust 3-pole (3 NO) industrial contactor engineered for motor control and resistive load switching. Part of the TeSys F family, this model is rated for AC-3 service at 185 A (≤440 V AC) and is designed for a 380 V AC control coil (40–400 Hz). It provides high breaking capacity, long mechanical life, and compatibility with standard TeSys accessories for reversing and multi-contactor assemblies.
