JJS-700 - 700Amp Fuse

JJS-700 - 700Amp Fuse

The JJS-700 is a 700A, 600VAC Class T fuse with a 200 kA interrupting rating at 600VAC, giving you clear electrical ratings to check against your equipment requirements. This very fast-acting, current-limiting fuse uses a knife-blade style configuration rather than leaving the physical format to guesswork. It measures 4.328 inches high by 2.5 inches wide by 2.5 inches deep and has a non-indicating design. Those details matter when you’re trying to identify the correct fuse for existing electrical equipment, particularly when multiple components may share a similar appearance.

Key Features and Benefits

• 700A rating: Provides the specified 700-amp rating for equipment designed around this fuse capacity.
• 600VAC voltage rating: Suitable for applications specifically requiring a fuse rated at 600VAC.
• Current-limiting Class T design: Combines the specified Class T format with current-limiting characteristics.
• Knife-blade style: Gives you an additional physical compatibility point to verify rather than relying on amperage and voltage alone.
• Non-indicating configuration: The JJS-700 does not incorporate a visual fuse-status indicator.

Material Compliance and Certifications

No specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information was provided for the JJS-700. These approvals should not be inferred from the JJS designation, electrical ratings, or Class T classification. Where a particular certification is required, confirm the markings on the actual fuse and consult the appropriate authoritative product documentation.

Where It Works Best

The JJS-700 700A Class T fuse is intended for compatible electrical equipment that specifically requires a 700A, 600VAC, very fast-acting, current-limiting Class T fuse with a 200 kA interrupting rating at 600VAC. The knife-blade style, non-indicating configuration, and stated physical dimensions matter as much as the electrical ratings when evaluating whether the fuse fits an existing application.
