KLSR225 - 225Amp Fuse

KLSR225 - 225Amp Fuse

When your equipment calls for a 225A Class RK1 fast-acting fuse, the details beyond amperage are just as important. The KLSR225 is a 225-amp, fast-acting, current-limiting fuse featuring the KLSR Series' single-element silver-link design. It is rated for a maximum of 600VAC and 300VDC, with an interrupting capacity of 200,000A at 600VAC and 20,000A at 300VDC. For a replacement, don't stop at "225 amps"—confirm the fuse class, opening characteristic, AC or DC voltage, interrupting capacity, physical configuration, and equipment requirements.

Key Features and Benefits

• 225A continuous current rating for equipment requiring a 225-amp Class RK1 fuse.
• Class RK1 configuration series is a defined fuse class for accurate replacement matching.
• Fast-acting (F) operation provides fast overload and short-circuit protection.
• Built around a single-element silver-link design, as specified for the KLSR don'ts.
• Current-limiting design helps reduce equipment damage caused by the heating and magnetic effects associated with short-circuit currents.
• Rated for systems up to 600VAC.
• Supports properly specified DC applications up to 300VDC.
• Knife-blade construction provides the physical format specified for KLSR225.
• Non-indicating design with no integral blown-fuse indicator specified.
• Installs using a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLSR Series as using a single-element silver-link design. No complete product-specific material composition is provided for KLSR225, so do not assume the construction materials of the body, terminals, filler, and other components beyond the stated silver link.

Where It Works Best

The KLSR225 225A fuse suits equipment designed for a 225A, Class RK1, fast-acting, current-limiting fuse with the corresponding voltage, interrupting, and physical requirements. The manufacturer specifically identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the fast-acting characteristics of the KLSR Series can be useful. Its current-limiting design is intended to reduce equipment damage caused by the heating and magnetic effects of short-circuit currents.
