TeSys D contactor coil 9-38A 400VAC LXD1V7

Contactor coil – reliable circuit starting and protection

The LXD1V7 coil is a dedicated replacement for TeSys D contactors, ensuring correct operation of control circuits. It is a key element in power systems, enabling efficient switching of electrical circuits on and off. Its versatility makes it suitable for both new installations and modernization of existing ones.

Construction and application

The coil is designed to work with 3- and 4-pole contactors of the LC1 D09 to D38 and LC1 DT20 to DT40 series. It provides reliable operation in the voltage range of 400VAC at a frequency of 50/60Hz. Its construction has been optimized for effective electromagnetic action, which translates into a quick and precise response to the control signal. This allows for smooth starting and stopping of connected receivers.

Key features and benefits

• Compatibility: Trouble-free replacement of a damaged coil in a wide range of TeSys D contactors, minimizing downtime in installation operation.
• Rated voltage: Adapted to standard network voltages of 400VAC (50/60Hz), which facilitates integration with existing systems.
• Durability: Designed to operate in harsh industrial conditions, resistant to vibrations and temperature changes (up to 60°C).
• Compliance with standards: Meets Green Premium requirements (RoHS/REACH), which guarantees safety of use and minimal environmental impact. This is important for both installers who care about compliance with regulations and end-users looking for ecological solutions.
• Easy installation: Simple replacement allows for quick restoration of contactor efficiency without the need for specialized tools or lengthy training.
• Wide range of applications: Ideal for controlling electric motors, lighting, heaters and other devices requiring frequent switching on and off.

Assembly and operation

Coil replacement should be performed by a qualified electrician in accordance with applicable safety regulations. Before starting work, disconnect the power supply to the circuit. After replacing the coil, check the correctness of the electrical connections and test the operation of the contactor. Regular checks of the coil's technical condition and the cleanliness of the surroundings will ensure long-term and trouble-free operation of the device. If any irregularities are noticed (e.g. overheating, mechanical damage), the coil should be replaced with a new one immediately.
