Product details

Overview

The LC1F1854 is a TeSys F 4-pole contactor rated 275 A in AC-1 utilization category for resistive loads, with a 1850 A making capacity and 1.48 kA breaking capacity per IEC 60947-4-1. It carries a 24 V coil drawing 8.9 W holding power, mounts to a plate, and is sealed to IP2X with TH protective treatment for damp environments.

Compared to the 3-pole LC1D150P7 rated 250 A, the LC1F1854 adds a fourth pole and 25 A more continuous current — 275 A vs 250 A — making it the choice when a neutral or auxiliary pole must switch the same resistive load without a separate contactor.
