SCLR300 - 300 Amp Fuse

SCLR300 - 300 Amp Fuse

When you replace a fuse in an industrial electrical system, getting the details right matters; amperage is only part of the picture. You also need the correct voltage rating, fuse class, operating characteristics, and physical size. The Eaton Edison SCLR300 Fuse brings those specifications together in a 300 Amp, 600V AC cartridge fuse with a 200kA interrupting rating. Designed with fast-acting, current-limiting characteristics, it provides overcurrent protection for compatible equipment where a Class RK1 fuse is specified. Whether you're servicing electrical distribution equipment or replacing a specified SCLR300 fuse, matching these details is the key to choosing the right component.

Key Features and Benefits

• 300 Amp Rating: Intended for electrical circuits that specifically require a 300A fuse.
• 600V AC Voltage Rating: Designed for compatible AC applications operating within the fuse's rated voltage.
• Fast-Acting Operation: Responds to overcurrent conditions according to its fast-acting time-current characteristics.
• Current-Limiting Protection: Helps reduce fault-current let-through during qualifying short-circuit conditions.
• Class RK1 Fuse Design: Provides a defined fuse classification for equipment compatibility and protection coordination.
• Rejection-Style Configuration: Helps prevent certain incorrect fuse substitutions when installed in a compatible rejection-type fuseholder.
• Non-Indicating Design: Does not include a built-in visual indicator showing whether the fuse has opened.
