Power disconnect switch LN2, 3-pole 200A LN2-200-I 112003

Power Disconnector – Reliable Power Disconnection

This 3-pole LN2 power disconnector with a current of 200A is a robust solution for safely disconnecting electrical circuits. It is suitable for both industrial installations and public buildings where reliability and high resistance to working conditions are required. The device is designed for fixed mounting, ensuring stability and long-term functionality.

Functionality and Application

The LN2-200-I disconnector serves as a main and maintenance disconnector, allowing for safe power disconnection during maintenance or repair work. Its construction based on IEC and VDE standards guarantees compliance with applicable safety standards. The rated operating voltage in the range of 690…690 V AC and the rated current of 200 A make it suitable for a wide range of applications. The possibility of using an optional overvoltage release further increases the functionality of the device, allowing it to be adapted to the specific needs of the installation.

• Versatility: Can function as a main, emergency, and maintenance disconnector.
• Safety: Provides effective circuit isolation, protecting against accidental contact with live conductors (IP20 protection class).
• Durability: Made of high-quality materials, guaranteeing long life and reliable operation even in harsh conditions.
• Compatibility: Common accessories with LZM/LN and NZM/N series circuit breakers simplify the selection of additional elements (remote drives, releases, auxiliary contacts).
• Mounting Flexibility: Possibility of direct and plate mounting ensures easy integration with different types of switchboards.
• High Short-Circuit Capacity: Withstood short-circuit current IcW is 3.5 kA, providing protection for the installation in the event of a short circuit.
• Suitable for Operation in Harsh Conditions: Rated operating power for AC-23 at 400 V is as high as 110 kW.

Construction and Parameters

The LN2-200-I disconnector is characterized by a solid, fixed-mounted construction. It has a lever as an actuating element and a locking mechanism for increased safety. The connection of the main contacts is made using a screw connection, ensuring a secure and durable connection of the conductors. The device is equipped with a gray control element for easy identification. The mechanical endurance confirmed by 20,000 switching cycles confirms its reliability in long-term operation. The permissible conductor cross-sections for connection range from 4 mm² to 185 mm², providing great freedom in choosing the appropriate cables.
