JJS-50 - 50Amp Fuse

JJS-50 - 50Amp Fuse

A replacement fuse requires more than one box to check, and the Eaton Bussmann JJS-50 series gives you several concrete details to verify before it goes into service. This 50A, 600V Class T fuse carries a manufacturer-specified 200 kAIC interrupting rating at 600VAC. It uses a ferrule-to-ferrule connection. Whether you're replacing a fuse during scheduled maintenance or identifying the correct component for existing equipment, this fuse is a reliable choice.

Key Features and Benefits

• 50A amperage rating: Clearly specified for equipment designed to use a 50-amp Class T fuse.
• 600V rating: Provides the stated voltage rating needed when checking the fuse against the application's electrical requirements.
• Class T fuse: The Class T designation gives technicians another essential specification to confirm rather than relying on amperage or appearance alone.
• Ferrule-to-ferrule connection: Uses a ferrule end-to-ferrule end configuration for compatibility with equipment designed around this connection style.
• Non-indicating design: The fuse does not incorporate a visual fuse-status indicator.

Where It Works Best

The Eaton Bussmann JJS-50 50A Class T fuse is best suited to compatible electrical equipment that specifically calls for a 50A, 600V Class T fuse with a 200 kAIC interrupting rating at 600VAC. The equipment should also support a ferrule-to-ferrule connection and accommodate its 1.56 x 0.81 x 0.81-inch dimensions.
