Schneider Electric LC1D38F7 3-Pole Contactor 38A 110V AC with 1NO+1NC Auxiliary Contacts

The Schneider Electric LC1D38F7 is a robust 3-pole power contactor engineered for demanding industrial environments. Designed to handle a rated operational current of 38A, this device provides reliable switching and motor control capabilities. It operates with a 110V AC control circuit and includes integrated auxiliary contacts, specifically one normally open (NO) and one normally closed (NC) contact, which facilitate seamless integration into complex control and automation systems.

Advantages

This contactor stands out for its high durability and consistent performance in heavy-duty electrical applications. Its compact design allows for efficient use of space within control panels, while the inclusion of auxiliary contacts provides added flexibility for monitoring and interlocking functions. The device is built to withstand frequent switching operations, ensuring long-term reliability and reduced maintenance requirements in industrial settings.

Suitable for

• Industrial motor control systems
• Power switching for heating and lighting circuits
• Automation and control panel integration
• HVAC system management

When it may not be suitable

This contactor is designed specifically for 110V AC control circuits. It is not suitable for applications requiring DC control voltages or systems where the operational current exceeds the 38A rating. Additionally, it should not be used in environments that exceed the specified environmental protection ratings without appropriate enclosure protection.

Key specifications

• Number of poles: 3
• Rated operational current: 38A
• Control circuit voltage: 110V AC
• Auxiliary contacts: 1 NO + 1 NC
• Mounting type: DIN rail or panel mount

How to use

The device should be installed by a qualified professional in accordance with local electrical regulations. It is typically mounted on a standard DIN rail or secured directly to a panel backplate. Connect the power cables to the main terminals and the control wiring to the coil and auxiliary contact terminals. Ensure all connections are tightened to the manufacturer's specified torque to prevent overheating and ensure secure electrical contact.

What to consider before purchase

• Verify that your control circuit voltage is exactly 110V AC.
• Ensure the 38A current rating is sufficient for your specific motor or load requirements.
• Check available space in your electrical enclosure for mounting.
• Confirm that the auxiliary contact configuration meets your control logic needs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of wear or debris accumulation to maintain optimal performance and safety standards.
