FAQs
Install with the system de-energized, verify the 1000 A rating matches the circuit, and mount the fuse into bolted blade end terminals. Tighten connections to manufacturer torque recommendations and ensure clearances around the fuse for cooling. Use appropriate PPE and consult the data sheet for any panel-specific gaps or mounting guidelines.
It provides current-limiting protection at 300 Vac/170 Vdc with a high interrupt rating of 200 kAIC at 300 Vac and 100 kAIC at 170 Vdc, along with Class T fast-acting characteristics. These features minimize arc energy and fault duration in drive-fed circuits, reducing downtime and collateral damage.
Yes. The JJN-1000 is CE marked and RoHS compliant, aligning with European safety and environmental standards. This simplifies cross-border procurement and supports compliance programs in industries such as aerospace, automotive, and general manufacturing.
Class T fuses are designed for fast-acting protection, interrupting fault currents quickly to limit energy transfer. This is advantageous in motor drives where rapid disconnection reduces wear on contacts and minimizes nuisance tripping during startup surges, improving overall drive reliability.
This is a non-indicating fuse designed for replacement after fault events or scheduled maintenance. Maintain a stock of same-model replacements for quick swaps, and verify compatibility with bolted blade end connections during panel refurbishment to maintain consistent contact integrity.
