Disconnect switch INS80 80A 3P 28904

Isolator switch – reliable power disconnection

The INS80 isolator is a three-pole device designed for the safe disconnection of electrical circuits. The rated continuous current of 80A makes it ideal for use in electrical installations with medium and high power. The device's design, with a long rotating handle, ensures convenient and intuitive operation for both installers and end-users.

Construction and application

The device is designed as a main and repair isolator, which means it can be used to completely cut off the power supply for maintenance or repair work. The possibility of mounting on a plate, in distribution boards and centrally on the front increases its versatility and allows it to be adapted to different installation configurations. Made of high-quality materials, it ensures durability and reliable operation for a long time. The locking mechanism additionally protects against accidental switching on during service work.

Key features and benefits

• High resistance to environmental conditions: IP40 protection degree guarantees protection against contact and ingress of solid bodies, making it suitable for use in various industrial and commercial environments.
• Safety of use: As an isolating switch, it provides a visible disconnection of the circuit, which is crucial for safety during maintenance work.
• Versatile mounting: The possibility of mounting on a plate, in distribution boards and centrally on the front facilitates integration with existing electrical infrastructure.
• Durability and reliability: Solid construction and high quality of workmanship ensure long-lasting and trouble-free operation of the device.
• Rated short-circuit current: Withstands short-circuit current up to 36 kA, providing protection for the installation in the event of a failure.
• Adapted for operation with higher voltage: Rated operating voltage up to 690 V allows for use in a wide range of applications.
• Screw connection: Provides a secure and durable connection of wires.
• Rated AC-23 operating power (400V): 37 kW – allows operation of devices with significant power.

Additional information: the device does not have auxiliary contacts (normally closed or normally open), and is also not intended to function as an emergency switch or safety isolator. Its construction is a permanently mounted device, which ensures stability and reliability of operation.
