FAQs
Begin with power isolated and verify the circuit rating matches the 70 A amperage of the JJN-70. Align the bolted blade ends with the panel bus or fuse holder, tighten to the manufacturer’s torque spec, and ensure a clean, vibration-free mounting. Use the standard packaging (five units) to stock backups and simplify future replacements.
The JJN-70 provides a 70 A amperage rating with a current-limiting behavior, offering 20 kAIC at 160 Vdc and 200 kAIC at 300 Vac. The voltage rating is 300 Vac and 160 Vdc, enabling reliable protection for both AC drives and DC bus sections in industrial equipment.
Yes. The JJN-70 is designed for VFD line protection, delivering fast fault interruption and limiting arc energy in motor drive systems. Its Class T fast-acting behavior and bolted blade connections support reliable protection in harsh industrial environments commonly found in manufacturing settings.
The JJN-70 is CE marked and RoHS compliant, aligning with European regulatory requirements for electrical components. These certifications simplify compliance during audits and support procurement processes in facilities that mandate RoHS conformance and CE certification for electrical protection devices.
The JJN-70’s current-limiting action reduces harmful fault energy, lowering repair costs after faults and extending drive life. Its robust bolted-blade design provides durable service in vibration-prone panels, while standard packaging and readily available data sheets streamline maintenance planning and spare parts logistics, contributing to lower total cost of ownership.
