Contactor Schneider Electric LC1D09BD — AC power supply, IP20, 3-pole, 9A, green/grey

Schneider Electric LC1D09BD is a compact 3-pole contactor designed for AC power switching up to 9 A. Intended for motor control, lighting and general switching duties, this device combines a narrow modular footprint with a green/grey housing and standard terminal layout to simplify panel integration and maintenance. The unit provides a 24 V DC coil with built-in transient suppression, screw-clamp connections and an auxiliary contact set (1 NO + 1 NC) for control-circuit feedback.

Advantages

The contactor offers reliable switching performance for AC-3 motor loads up to 9 A and suitable apparent power at 400 V, a compact 45 mm width that saves space in control cabinets and flexible mounting on DIN-rail or by screws. Its IP20 degree of protection and standardized terminal arrangement streamline installation and servicing. Built to operate at ambient temperatures up to 60°C and to withstand frequent switching up to 3600 cycles/hour, it meets multiple international standards for safety and compatibility.

Suitable for

• Motor starters and small motor control circuits (up to 4 kW at 400 V)
• Lighting and auxiliary AC switching in control panels
• Machine control and automation where a compact, modular contactor is required
• Applications requiring 24 V DC coil control with transient suppression

When it may not be suitable

This contactor is not intended for direct switching of loads that exceed the specified AC-3 rating or continuous currents above 9 A; for larger motors or higher continuous currents select a contactor with a higher rated current. The IP20 protection rating means the device is not suitable for exposed outdoor locations or environments with significant dust or water ingress without additional enclosure protection.

Key specifications

• Poles: 3 (three-pole)
• Rated operational current: 9 A (AC-3)
• Rated operational voltage: up to 690 V AC (application dependent), typical rating for 400 V systems
• Coil control: 24 V DC with transient suppressor
• Auxiliary contacts: 1 NO + 1 NC (built-in)
• Connection type: screw clamp terminals
• Protection rating: IP20
• Mechanical width: 45 mm (compact modular format)
• Mounting: DIN-rail or screw fixing
• Operating ambient temperature: up to 60°C
• Switching frequency: up to 3600 cycles/hour

How to use

Mount the contactor on a DIN-rail or secure it with screws in a suitable control cabinet that provides protection against dust and moisture. Connect power conductors to the main terminals and route the 24 V DC control wiring to the coil terminals, observing correct polarity. Use the built-in 1 NO + 1 NC auxiliary contact for control logic feedback or interlocks. Follow applicable wiring diagrams and torque values for screw clamps, and verify correct functioning by testing control inputs and load switching under no-load conditions before placing into normal operation.

What to consider before purchase

• Confirm the motor or load type and ensure the AC-3 rating and 9 A current are sufficient
• Verify the control coil voltage is 24 V DC and compatible with your control system
• Ensure your installation environment is compatible with IP20 protection or plan an enclosure
• Check mounting space — 45 mm width and DIN-rail compatibility
• Consider required certifications and standards compliance for your application

Usage recommendations

Use this contactor within its rated AC-3 current and voltage limits, provide appropriate overload and short-circuit protection, and install in a protected control cabinet for reliable long-term operation. Regularly inspect terminal tightness and contactor operation as part of preventive maintenance.
