KLSR035 - 35Amp Fuse

KLSR035 - 35Amp Fuse

When your equipment calls for a 35A Class RK1 fast-acting fuse, the KLSR035 provides a specific set of electrical and physical characteristics to match. The KLSR035 is a single-element, silver-link, current-limiting fuse rated for up to 600VAC and 300VDC. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications for this fuse family. Physically, the KLSR035 is a non-indicating industrial cartridge fuse designed for installation in a compatible fuse block, clip, or holder; the LFR60060 Series is the corresponding holder series. For a proper replacement, match more than the 35A rating—verify Class RK1, voltage, interrupting capacity, fast-acting operation, physical configuration, and holder compatibility.

Key Features and Benefits

• 35A continuous current rating for equipment requiring this specific fuse amperage.
• Class RK1 configuration provides a defined fuse class for accurate replacement matching.
• Fast-acting (F) operation delivers quick overload and short-circuit protection.
• Uses a single-element silver-link design, a defining construction feature of the KLSR Series.
• Current-limiting construction helps reduce damage caused by the heating and magnetic effects of short-circuit currents.
• Rated for electrical systems up to 600VAC.
• Supports DC applications up to 300VDC when the complete circuit requirements are compatible.
• Industrial cartridge construction provides the specified physical fuse format.
• Non-indicating design for applications that do not require integral fuse-status indication.
• Designed for installation using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information confirms that the KLSR035 uses a single-element silver-link design. It also identifies the product as a Class RK1, fast-acting, current-limiting fuse. The supplied specifications do not provide a complete product-specific material composition beyond the silver-link information.

Where It Works Best

The KLSR035 35A fuse best matches electrical equipment designed for a 35A Class RK1 fast-acting, current-limiting fuse with the KLSR035's corresponding electrical and physical requirements. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where the fast-acting KLSR design can be useful. Its current-limiting characteristics are also intended to reduce equipment damage associated with the heating and magnetic effects of short-circuit currents.
