Schneider Electric Square D LC1D115U7 115 240V AC 3P Contactor

Industrial IEC Magnetic Contactor

The Schneider Electric Square D LC1D115U7 is a three-pole IEC magnetic contactor built for motor control and resistive load switching in industrial panels. It carries a 115 A rating and operates from a 240V AC coil, making it suitable for standard industrial control circuits. The unit includes one normally open and one normally closed auxiliary contact for signalling or interlocking duties. Screw clamp terminals provide secure field wiring without specialised tooling.

Coil Voltage and Auxiliary Limits

The 240V AC coil restricts use to control circuits that supply exactly that voltage; other coil voltages require a different contactor. Auxiliary switching is limited to a single 1NO/1NC pair, so applications needing multiple status signals or complex interlocking must add separate relays. The non-reversing design means the contactor cannot change motor direction on its own; a reversing starter assembly would be required for that function. Physical depth of 5.12 inches and height of 4.33 inches define the minimum enclosure space needed for installation.

115 Ampere Current Rating

The decisive specification is the 115 A main-contact rating, which determines whether the contactor can handle the intended motor or heater load. If the connected equipment draws more than 115 A, this model is undersized and a higher-rated contactor must be selected. Conversely, loads well below this rating may be served by a smaller, more economical unit. Matching the contactor rating to the actual full-load current ensures reliable operation and compliance with IEC coordination tables.
