KRP-C-1900SP - 1900Amp Fuse

KRP-C-1900SP - 1900Amp Fuse

The KRP-C-1900SP is a 1900A Class L fuse for electrical equipment that requires a high-amperage fuse with clearly defined AC and DC ratings. It carries a 600VAC and 300VDC voltage rating, along with an interrupt rating of 300 kAIC at 600VAC and 100 kAIC at 300VDC. The manufacturer specifies a response time of 4 seconds at 500%, while its non-indicating design means this particular catalog number does not provide a built-in visual fuse-status indication. If you're replacing a fuse, don't stop after finding "1900A" on the label. Confirm the fuse class, AC or DC voltage, interrupting capacity, response characteristic, physical dimensions, and indicating status against the equipment specifications before matching.

Key Features and Benefits

• 1900A current rating provides an exact amperage reference for equipment requiring this Class L configuration.
• Rated for 600VAC, supporting equipment specifically designed around that maximum AC voltage rating.
• It is also rated for 300VDC, giving the KRP-C-1900SP a documented DC voltage specification.
• Class L designation helps buyers distinguish this fuse from products with different fuse-class requirements.
• The manufacturer-listed response time of 4 seconds at 500% gives you another key characteristic to compare with equipment specifications.
• The non-indicating design makes the fuse-status configuration clear before installation.
• RoHS compliant, as confirmed in the supplied manufacturer specifications.
• CE marked, providing another documented compliance attribute.

Where It Works Best

The KRP-C-1900SP suits electrical equipment that requires a 1900A Class L fuse with the corresponding electrical and physical characteristics. For AC equipment, confirm compatibility with the 600VAC maximum voltage rating and 300 kAIC interrupt rating at 600VAC. For DC equipment, compare the system requirements with both the 300VDC rating and the 100 kAIC interrupt rating at 300 VDC.
