Disconnect switch with fuses FLBS 400 3P 004661803

Disconnector with fuses – solid circuit protection

This three-pole disconnector with FLBS 400 3P fuses is a reliable solution for protecting electrical installations. Designed for both plate and panel mounting, it provides effective isolation and protection against overloads and short circuits. Its construction allows for easy integration with existing systems, and the screw connection of the main contacts guarantees stable and secure connections.

Functionality and application

The device combines the functions of a main disconnector and a safety disconnector, making it a versatile element in any installation. The thermal current Ith of 400A and the rated operating current Ie AC-21 at 415V of 400A allow it to be used in circuits with high loads. The rated insulation voltage of 1000V ensures safety even in demanding working conditions.

• Ideal for building electrical switchboards.
• Can be used in industrial, commercial and public utility buildings.
• Provides safe disconnection of circuits during maintenance or repair.
• Allows easy replacement of fuses without having to disconnect the entire installation.

Characteristics and mounting

The design of the FLBS 400 3P disconnector has been designed with ease of installation and reliable operation in mind. The IP00 protection class indicates no protection against the ingress of solids and water – therefore, the device should be mounted in enclosures providing adequate protection against external conditions. The fuse insert size compliant with DIN standard (2…) simplifies the selection of appropriate protective elements. Thanks to the possibility of mounting both on a plate and a panel, it can be easily adapted to the specifics of a particular installation. The weight of the device is approximately 6.25 kg, and its dimensions (256 x 240 x 180 mm) should be taken into account when planning the mounting space.
