Fuse isolation switch – reliable installation protection

This fuse isolation switch, designed for panel mounting, is a key element in electrical power distribution systems. It provides effective protection of electrical equipment against the effects of short circuits and overloads through cooperation with industrial NH2 type fuse links. The device's construction allows for safe disconnection of circuits for maintenance or repair work.

Construction and application

The switch is characterized by three poles and is adapted to operate with a rated voltage of up to 690 V AC and a continuous current of up to 400 A. Bridge terminals (S) with a range of 50-185 mm² allow connection of wires of various thicknesses, ensuring installation flexibility. The device has a protection degree of IP20, which means protection against touching with a finger and solid bodies larger than 12.5 mm. Made of high-quality materials, it guarantees durability and reliable operation even in demanding conditions.

Key features and benefits

• High short-circuit resistance: The rated conditional short-circuit current Iq is 100 kA, which ensures effective protection of the installation in the event of a failure.
• Versatile application: Designed to work with NH2 fuse links, commonly used in industry and construction.
• Easy installation: The construction allows for panel mounting, and the bridge terminals facilitate wire connection.
• Safe use: The IP20 protection degree minimizes the risk of electric shock.
• Solid construction: Ensures long-lasting and reliable operation of the device.
• Adapted to work in difficult conditions: The rated insulation voltage is 690 V, which ensures safety even with higher network voltages.
• Lid handle as an actuator: Enables convenient and intuitive control of the switch.

This switch is a solid solution for both professional installers and end-users looking for reliable protection of their electrical installations. Its versatility and ease of installation make it ideal for a wide range of industrial and construction applications.
