Contactor Schneider Electric LC1D12P5 (STYCZ.TESYS D) 3-pole AC3 12A 230VAC 1NO 1NC

Schneider Electric LC1D12P5 (STYCZ.TESYS D) is a three-pole AC contactor designed for switching and controlling three-phase loads in industrial and commercial installations. Rated for AC-3 duty with a main current of 12 A and a 230 VAC coil, this contactor combines compact dimensions and reliable electrical performance. It includes one normally open and one normally closed auxiliary contact to support control circuits and interlocks, enabling basic automation and motor control tasks.

Advantages

The contactor provides dependable switching for motors and resistive loads within its rated AC-3 category, ensuring consistent operation at 12 A. Its 230 VAC coil is compatible with common control voltages, and the integrated auxiliary contacts simplify wiring for start/stop and signaling functions. The compact, modular design allows for space-efficient installation in control panels and integration with standard mounting accessories.

Suitable for

• Switching three-phase motors up to the rated AC-3 current
• Control circuits requiring one normally open and one normally closed auxiliary contact
• Compact control panels and machine automation with limited space
• Industrial lighting and resistive load switching within rated parameters

Key specifications

• Poles: 3
• Rated operational current (AC-3): 12 A
• Coil voltage: 230 VAC
• Auxiliary contacts: 1 normally open (1NO), 1 normally closed (1NC)
• Intended use: motor switching and general-purpose AC control
• Mounting: panel or DIN-rail compatible modular form factor

How to use

Install the contactor in a clean, ventilated control cabinet and secure it according to the manufacturer's mounting recommendations. Connect the three-phase load to the main output terminals and the supply lines to the main input terminals, observing correct phase sequence. Wire the 230 VAC control supply to the coil terminals and incorporate the auxiliary contacts into the control circuit for start/stop commands, interlocks, or status feedback. Verify all connections, ensure appropriate overcurrent protection is in place, and test operation under no-load conditions before commissioning.

Использование и обслуживание

Regularly inspect electrical connections for tightness, check for signs of overheating or wear, and ensure the contactor operates within its specified ratings. Replace the device if contacts become pitted or if mechanical operation becomes unreliable.
