SCHNEIDER ELECTRIC LC1D09 / LAD4RCU 038545

Schneider Electric LC1D09 TeSys D Contactor with LAD4RCU Suppressor Description This is a Schneider Electric TeSys D series 3-pole contactor, model LC1D09. It is designed for high-reliability motor control applications. This unit comes pre-fitted with an LAD4RCU RC suppression module, making it suitable for circuits with a coil voltage of 110V to 250V AC. It offers a compact design, easy installation on a DIN rail, and a long mechanical and electrical life.

FAQ What is the purpose of the included LAD4RCU module?The LAD4RCU is an RC (Resistor-Capacitor) suppression module. It is connected across the contactor’s coil (A1-A2 terminals) to dampen the high voltage spike that occurs when the coil is de-energized. This protects sensitive control electronics like PLC outputs from electrical noise and damage. Can I use this LC1D09 contactor without the LAD4RCU module?Yes, the contactor can function without the module. However, the coil’s electrical characteristics and the required control voltage will be different. You would need to verify the specific coil code (e.g., F7 for 110V AC, P7 for 230V AC) printed on the contactor’s body to ensure compatibility with your control circuit. The suppressor is highly recommended for PLC-controlled systems. What are the AC-1 and AC-3 ratings and when should I use them?The AC-3 rating (9A, 4kW at 400V for this model) is for inductive loads like squirrel-cage motors during starting. The AC-1 rating (Ith: 25A) is for non-inductive or slightly inductive loads, such as resistance heaters or lighting. Always use the AC-3 rating for motor applications, as it accounts for the high inrush current.
