Product details

Overview

The LC1F780 is a Schneider TeSys F full-voltage, non-reversing contactor rated for 780 A switching current across AC-1, AC-3, and AC-4 utilization categories, handling resistive and motor loads on a 460 V supply. It carries a 110 V coil drawing 44 W, breaks up to 6.24 kA Icu, and is certified to IEC 60947, UL, CSA, CE, plus marine approvals including DNV, ABS, and Lloyds.

Compared to the TeSys K LC1K09004F7 (20 A, 4-pole, 110 A making capacity), the LC1F780 delivers 780 A switching current and 7800 A rated making capacity, making it the correct choice for high-current motor or resistive loads above 100 A.

The LC1F780 is an active TeSys F catalog item; lead time is quoted per RFQ.
