The Schneider Electric LC1E18004V7IN is a 4-pole (4NO) contactor from the Easy TeSys Control range, rated for 40 A in AC-1 utilisation category at up to 415 V. AC-1 means it is designed for resistive loads — heaters, lighting banks, or other non-inductive circuits — where the switching current is essentially the same as the load current. The 400 V coil suits standard three-phase control circuits in industrial panels. The IP2X degree of protection means it is finger-safe from the front but not sealed against moisture — suitable for dry indoor panel environments.
It also meets GB/T 14048 equivalents for the Chinese market.
