Fuse disconnect switch with blown fuse indication Z-SLS/CB/3 248249

Fuse disconnect switch – reliable protection for electrical installations

The Z-SLS/CB/3 fuse disconnect switch from Eaton is a key element of every electrical installation, providing effective protection against the effects of short circuits and overloads. The device is designed to work with D02 fuse cartridges, offering versatility for use in both domestic and industrial installations. A characteristic feature of this model is the fuse blown indication function, which facilitates quick identification of the problem and minimizes system downtime.

Functionality and application

The Z-SLS/CB/3 disconnect switch not only allows you to disconnect fault and operating current, but also to create a visible insulating gap after removing the fuse cartridge – important for safety during maintenance work. Therefore, it finds application in main distribution boards, distribution networks and industrial electrical installations. Mounting is done on a standard TH35 mounting rail, ensuring easy and quick installation.

Key product features

• Fuse blown indication: Visual information about the need to replace the fuse cartridge, increasing safety and facilitating diagnostics.

• Locking mechanism preventing closing: The ability to secure the disconnect switch against accidental switching on with a padlock – an additional level of protection.

• Compatibility with D01 and D02 fuse cartridges: Versatility of use with different types of fuse cartridges.

• Sealing possibility: Protection against unauthorized access and manipulation.

• Three-pole design (3P): Provides comprehensive protection for three-phase electrical circuits.

• Rated current 63A: Suitable for protecting circuits with medium load.

• Rated voltage 400V: Standard network voltage in most installations.

• Size D02: Specifies the physical dimensions of the disconnect switch and compatibility with other installation elements.

Construction and mounting

The disconnect switch is characterized by a solid construction ensuring long-term and reliable operation. Mounting on the TH35 rail is simple and intuitive, and the compact dimensions of the device allow for optimal use of space in the distribution board. The device has three separable current paths, which ensures complete separation of phases and neutral (in the case of the 3+N version).

Compliance with standards and operating conditions

The disconnect switch meets the requirements of IEC/EN 60947-3, IEC/EN 60269-3 (DIN VDE 0636-3) and IEC/EN 61439-3 (VDE 0660-600-3) standards, which guarantees its safety and reliability. It is designed to operate at temperatures from -25°C to +40°C, making it suitable for most environmental conditions found in buildings and industrial plants. The IP20 degree of protection provides protection against finger contact and access to hazardous live parts.
