400A Three-pole Disconnector – Reliable Power Disconnection

This 400A rated power disconnector is a robust solution for safe and efficient disconnection of electrical circuits. Designed for both industrial and commercial applications, it provides reliable protection for electrical installations and equipment. Its design allows for mounting in distribution boards, on a plate, and frontally, offering great flexibility during installation.

Functionality and Application

The INV400 disconnector is designed for use in circuits with a rated voltage of 690V. It can be used as a main disconnector, maintenance disconnector, and in applications requiring frequent load switching. Thanks to the possibility of using additional auxiliary contact blocks (up to 4 pcs), it can be easily integrated with control and signaling systems. Made of high-quality materials, it guarantees long-lasting and trouble-free operation even in harsh conditions.

Characteristics and Benefits

• High short-circuit resistance: Rated conditional short-circuit current Iq at 150 kA provides effective protection against the effects of failures.
• Universal mounting: Possibility of mounting on a plate, in a distribution board and centrally on the front makes it easier to integrate with different types of installations.
• Safe operation: It has a locking mechanism that prevents accidental switching on or off of the disconnector during operation.
• Durable construction: The permanently mounted device is made of high-quality materials ensuring long life.
• High rated power: Rated operating power for AC-23, 400 V is as high as 200 kW, allowing it to handle even demanding loads.
• Suitable for working in difficult conditions: Protection class IP40 protects against access to live parts and ensures safety in industrial environments.
• Easy connection of wires: Screw connection of the main contacts ensures a secure and durable electrical connection.
• Long rotary handle: Allows for convenient and intuitive control of the disconnector.

Additional information: the disconnector does not have a built-in motor drive or optional voltage release. It is compatible with optional auxiliary contact blocks increasing the functionality of the device. The rated short-time withstand current Icw is 20 kA, which further increases its reliability in emergency situations.
