JJS-1000 - 1000 Amp Fuse

JJS-1000 - 1000 Amp Fuse

The JJS-1000 is easy to identify by its key specifications: 1000 amps, 600VAC, Class T, knife-blade style, and a 200 kA interrupting rating at 600VAC. When your application calls for a 1000A JJS Class T fuse, those details matter as much as the catalog number.

Key Features and Benefits

• 1000A rating: Designed for applications specifically requiring a 1000-amp fuse.
• 600VAC rating: Suitable where the equipment requirements call for the stated 600VAC fuse rating.
• Very fast-acting: The supplied product information identifies the JJS-1000 as a very fast-acting fuse.
• Current-limiting Class T fuse: Combines the specified Class T format with current-limiting characteristics.
• Knife-blade style: Provides a defined physical configuration that can be checked against the fuse holder and equipment requirements.
• Non-indicating design: This model does not incorporate an indicating feature.

Material Compliance and Certifications

No specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information was provided for the JJS-1000. These designations should not be assumed from the fuse class or part number alone. Where a particular certification or compliance standard is required, confirm the markings on the actual product and consult the applicable authoritative documentation.

Where It Works Best

The JJS-1000 1000A Class T fuse is best suited to compatible electrical equipment that specifically requires a 1000A, 600VAC, very fast-acting, current-limiting Class T fuse with a 200 kA interrupting rating at 600VAC. Its knife-blade style and stated dimensions also make it important to verify the physical interface and available space in the intended equipment.
