Disconnect switch 3P/160A SZ160.3

Fuse disconnect switch – reliable installation protection

The SZ160.3 fuse disconnect switch is a key element of every safe and efficient electrical installation. It is used to disconnect circuits under voltage and to protect against the effects of overloads and short circuits, ensuring the safety of people and equipment. This model, manufactured by ENSTO, is designed to work with NH00 type fuse links, which guarantees high efficiency and easy replacement. The three-pole (3P) design makes it an ideal solution for three-phase networks with a voltage of up to 415V and a rated current of 160A.

Construction and application

The SZ160.3 is distinguished by a solid construction, adapted for pole mounting. Made of durable materials, it ensures long-lasting and trouble-free operation even in harsh environmental conditions. Cable terminals allow connection of conductors with a cross-section from 16 to 120 mm², both aluminum and copper. The possibility of using plug-in connectors further facilitates and speeds up the installation and disassembly of the device. As a safety disconnect and main switch, it meets safety standards and provides full control over the electrical circuit.

Key advantages for professionals and users

• High reliability: Rated conditional short-circuit current at 50 kA guarantees effective protection against sudden surges.
• Versatility: Possibility of using both aluminum and copper conductors increases the range of applications.
• Easy installation: Cable terminals and the option of plug-in connectors greatly simplify the installation process.
• Safety: The safety disconnect function allows for safe disconnection of the circuit during maintenance or repair work.
• Compatibility: Designed for NH00 fuse links – widely available on the market.
• Durable construction: Made of high-quality materials ensures long device life.
• Cable entry direction from the side: Facilitates cable routing and improves installation aesthetics.

Thanks to these features, the SZ160.3 disconnect switch is an optimal solution for both professional installers and end-users looking for reliable protection of their electrical installations.
