  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Reliable motor control with 24V AC coil voltage
  • Secure connections via screw clamp terminals
  • Auxiliary contacts 1NO/1NC for flexible circuit design
  • Durable performance rated to 1.5 Mcycles electrical life
  • Versatile DIN rail or plate mounting options

IEC three-phase contactor

The Schneider Electric LC1D40AB7 is a non-reversing magnetic contactor built for motor control and resistive load switching. It uses a 24V AC coil and provides one normally-open and one normally-closed auxiliary contact for control circuits.

Sustained operation

Electrical durability reaches 1.5 Mcycles under specified conditions and the unit is rated for up to 3600 cycles per hour. Opening times range from 12 to 19 ms while closing times sit between 12 and 26 ms.

Installation notes

Mounting options include DIN rail or plate mounting with screw clamp terminals for secure wiring. The IP20 rating protects against finger contact and objects larger than 12 mm but does not guard against water ingress.

Questions about this item

How much heat and noise does the 24 V AC coil generate during continuous operation?

The coil runs at 24 V AC with closing times of 12 to 26 ms and opening times of 4 to 19 ms, so steady-state heat and audible hum are minimal for an IEC contactor of this class.

What control circuit and mounting hardware must I already have to install this contactor?

You need a 24 V AC control supply, screw clamp wiring for the coil and power terminals, and either a 35 mm DIN rail or a flat plate for mounting.

Will the 1 NO / 1 NC auxiliary contacts work with my existing 120 V AC pilot relays and 600 V AC motor starters?

Yes — the auxiliary block is rated for the same IEC 60947-4-1 duty as the main poles, so it can switch 120 V AC control circuits and interlock with 600 V AC starters without extra interfaces.
