KLNR175 - 175Amp Fuse

KLNR175 - 175Amp Fuse

The KLNR175 is a 175A Class RK1 fast-acting, current-limiting fuse for your electrical equipment that needs a quick response to overloads and short circuits. Its single-element silver-link design is a defining feature of the KLNR series, combining fast-acting operation with current-limiting performance.

Key Features and Benefits

• 175A continuous current rating for equipment specifically designed around a 175-amp fuse.
• Class RK1 fuse configuration provides a clearly defined replacement and application requirement.
• Fast-acting (F) operation provides fast overload and short-circuit protection.
• Rated for electrical systems requiring up to 250VAC or 125VDC within the specified application limits.
• The current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit currents.
• Uses the KLNR family's single-element silver-link design.
• Knife-blade construction provides the physical configuration specified for KLNR175.
• Non-indicating design, so this catalog number does not include an indication feature.
• Installs using a compatible fuse block, clip, or holder.
• LFR25200 Series is the holder series identified in the supplied specifications.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLNR175 as a Class RK1 fuse. It confirms its current-limiting family style, fast-acting operation, single-element silver-link design, electrical ratings, and knife-blade construction. The manufacturer information also covers applications that require the current-limiting ability of UL Class RK1 fuses.

Where It Works Best

The KLNR175 best matches electrical equipment that requires a 175A, 250VAC/125VDC, Class RK1 fast-acting current-limiting fuse with knife-blade construction. The manufacturer specifically points to variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the fast-acting characteristics of the KLNR/KLSR series can be useful. For AC applications, verify the circuit requirements against the fuse's 250VAC maximum and 200,000A interrupting rating at 250VAC. For DC applications, confirm compatibility with its 125VDC maximum and 20,000A interrupting rating at 125VDC.
