Schneider Electric LC1D18 TeSys D Contactor 3P 18A AC-3 7.5kW | Coil Voltage Options
Couldn't load pickup availability
The Schneider Electric LC1D18 is a TeSys D 3-pole power contactor rated 18 A in AC-3 (≈7.5 kW / 10 HP motors at 400 V), available with coil options 24 V AC, 48 V AC, 110 V AC, 220 V AC, 380 V AC, 24 V DC. It switches three-phase motors, heaters, lighting and other loads remotely from push buttons, PLCs, float switches, pressure switches or timers, and combines with TeSys overload relays and motor circuit breakers to form complete motor starters.

Selection guide
Select the contactor by the motor full-load current in AC-3 (not the motor kW alone), choose the coil voltage to match your control circuit (220 V AC is the most common in Egypt), and pair it with an overload relay whose range covers the motor current.
Frequently asked questions
What motor size can the LC1D18 control?
In AC-3 duty at 400 V it is rated 18 A, which corresponds to about 7.5 kW three-phase motors.
Which overload relay fits this contactor?
Use the TeSys thermal overload relay of the same frame (LRD / LRE / LR9 families) with a setting range that includes the motor nameplate current.
What does the coil code mean?
The suffix of the reference shows the coil voltage: M7 = 220 V AC, B7 = 24 V AC, E7 = 48 V AC, F7 = 110 V AC, Q7 = 380 V AC, BD = 24 V DC.
