FAQs
For reliable integration, use ferrule-end connections on standard terminals and ensure the fuse fits a compatible Class J holder. Verify the panel layout supports 2.25 in length and 0.81 in width, with adequate clearance for heat dissipation. Confirm that wiring polarity and conductor sizing meet the 3.2 A rating and the RoHS/CE requirements.
The fuse provides a 3.2 A amperage rating with 600 Vac and 300 Vdc voltage ratings, and a 300 kAIC interrupt rating at 600 Vac plus 100 kAIC at 300 Vdc. Its time-delay, dual-element design tolerates motor inrush while rapidly interrupting faults, delivering selective protection for low-voltage motor circuits.
Yes, the LPJ-3-2/10SP supports motor protection in多数 AC drive applications due to its time-delay characteristic and high inrush tolerance. However, ensure coordination with drive protections and consider phase current profiles to prevent nuisance trips while maintaining safe shutdown in fault conditions.
The LPJ-3-2/10SP is CE marked and RoHS compliant, aligning with European regulatory requirements for electrical products. These certifications support compliance in industrial panels and assemblies, helping you meet safety, environmental, and import/export standards across multiple regions.
The dual-element current-limiting design minimizes nuisance trips during motor start-up, reducing unplanned downtime. Its robust interrupt rating protects downstream equipment, potentially lowering repair costs. With standard packaging and ferrule ends, field replacement is straightforward, supporting lower maintenance labor and faster line recovery after fault events.
