Insulated disconnect switch with fuse RBK 1 PRO V 63-811748-031

Fuse disconnect switch – solid protection for installations

The RBK 1 PRO V fuse disconnect switch is a reliable device designed for safely disconnecting electrical circuits powered by NH1 fuse links. The design allows for panel mounting, ensuring convenience and aesthetics of the installation. The device is a key element in power distribution systems, guaranteeing effective protection against overloads and short circuits.

Construction and application

The RBK 1 PRO V disconnect switch has been designed with demanding industrial and commercial applications in mind. Made of high-quality materials, including self-extinguishing V0 class plastic, it ensures safe use even in harsh conditions. Designed to operate at a rated voltage of up to 690V AC and a continuous current of 250A, it is perfect for installations with high power. V-type cable lugs facilitate the connection of wires with a cross-section of up to 240mm².

• Panel mounting: Allows easy integration with existing electrical infrastructure.
• NH1 fuse links: Compatibility with popular NH1 fuse links provides a wide range of applications.
• V cable lugs: Ensure a secure and durable connection of wires.
• Self-extinguishing V0 plastic: Increases safety by limiting the spread of fire.
• Possibility of sealing: Protects against unauthorized access and manipulation.

Parameters and user features

The disconnect switch is characterized by high resistance to environmental conditions and mechanical strength. The rated short-time withstand current of 80kA guarantees effective protection of the installation during a short circuit. The IP30 protection class protects against accidental contact and access to live parts. The cover handle facilitates operation of the device, and the ability to check the status of the fuse link (no control in this model) allows for quick identification of any problems.

The rated conditional short-circuit current Iq is 0.08 kA, which demonstrates its ability to withstand short-term overvoltages without damage. The location of the drive element on the front side provides convenient access during operation. The device has three poles, allowing its use in three-phase circuits.
