LENRK400 - 400 Amp Fuse

LENRK400 - 400 Amp Fuse

The Eaton Edison LENRK400 provides precise electrical and physical specifications to compare when LENRK400 appears in your equipment record, maintenance schedule, or existing installation. This 400A Class RK1 fuse carries manufacturer-listed voltage ratings of 250 Vac and 125 Vdc, along with a 200 kAIC interrupt rating. Eaton lists the fuse as non-indicating and highlights high in-rush current motor protection as a special feature. For an accurate match, compare the catalog number, amperage, voltage, Class RK1 classification, interrupt rating, dimensions, certifications, and any other requirements documented for the equipment.

Key Features and Benefits

• 400 A amperage rating gives maintenance personnel a clear value to compare with the documented equipment requirement.
• Manufacturer-listed voltage ratings of 250 Vac and 125 Vdc identify both the AC and DC ratings supplied for LENRK400.
• Class RK1 classification clearly identifies the manufacturer's listed fuse class.
• Eaton specifically lists high in-rush current motor protection as one of the LENRK400's special features.
• Listed as non-indicating so that you can confirm the fuse-indicator configuration directly from the specification.
• RoHS Compliant, UL Listed, and CSA certified per the supplied manufacturer information.

Material Compliance and Certifications

The Eaton Edison LENRK400 is listed as RoHS Compliant, UL Listed, and CSA Certified in the supplied manufacturer specifications. No separate material composition was provided for this model, so we have not assumed any fuse-body, terminal, or component material.

Where It Works Best

The LENRK400 is relevant to evaluate when the equipment documentation specifies a 400A Class RK1 fuse rated for 250 Vac and/or 125 Vdc and a 200 kAIC interrupt rating. Eaton's listed high in-rush current motor protection feature is another product-specific characteristic to compare with the application requirements.

Physical compatibility needs its own check. The LENRK400 measures 8.63 × 2.36 × 2.36 inches, but the manufacturer information supplied does not specify a connection type or mounting method. Confirm those installation details separately rather than inferring them from other LENRK-series models. Start with the LENRK400 catalog number, then verify its electrical ratings, fuse class, dimensions, certifications, and installation-specific requirements before treating it as an exact replacement.
