Fuse disconnect switch R 303 16 A 3P 606704

Fuse disconnector – reliable installation protection

The R 303 insulated fuse disconnector is an element used to safely disconnect electrical circuits, as well as to protect against overloads and short circuits. Designed for mounting in distribution boards, it provides effective insulation and the ability to replace fuses without having to disconnect the entire installation. This model, with a rated current of 16A and a 3-pole design, is ideal for both professional installers and end-users looking for a reliable solution.

Functionality and application

This disconnector is not only a protective element, but also a convenient tool for servicing and maintaining electrical installations. Thanks to the possibility of indirect and plate mounting, its installation is flexible and adapted to different needs. The rated operating voltage in the range of 12…400 V and the switching capacity of up to 6.4 kW mean that it can be used in a wide range of installations – from domestic to industrial. The built-in locking mechanism further increases safety, preventing accidental opening of the circuit during operation.

Key features and benefits

• High resistance to short-circuit currents: The rated short-time withstand current Icw is as high as 50 kA, which guarantees effective protection of the installation in the event of a failure.
• Universal mounting: The possibility of indirect, plate and distribution board mounting makes it easy to integrate with various electrical systems.
• Safety of use: The locking mechanism prevents accidental opening of the circuit during operation, minimizing the risk of electric shock.
• Durable construction: The device made of high-quality materials ensures long-lasting and reliable operation.
• Easy connection of wires: Screw connection of the main contacts ensures a secure and durable connection of wires.
• IP40 degree of protection: Provides protection against touching live parts and against the ingress of solid objects larger than 1 mm.
• Compliance with standards: The product meets the required safety standards, which confirms its high quality and reliability.
• Designed as a main disconnector: Allows complete disconnection of the circuit for maintenance or repair work.
