FAQs
Yes. KRP-C-3500SP uses bolted blade end x bolted blade end terminations, a standard connection style that simplifies panel wiring, reduces the risk of loose contacts, and supports reliable, vibration-resistant installations in new builds or retrofits.
The fuse is rated for 3500 A with a 600 V rating and 300 kAIC interrupt capacity, plus a 4 second response time at 500%. These specs enable selective protection for heavy feeders and motors, limit arc energy, and improve fault-coordination with upstream devices to minimize downtime.
Best for high-current motor feeders, switchgear, and power distribution panels in manufacturing and process facilities. It supports large-scale equipment protection, reduces unplanned outages, and aligns with demanding industrial protection schemes.
The KRP-C-3500SP is RoHS compliant and CE marked, aiding regulatory compliance for global procurement. While not UL-listed in the provided data, these certifications help streamline multi-market sourcing for electrical protection components.
With readily available data sheets (No. 1009) and full catalogs, sizing and replacement planning are faster, reducing commissioning time. The current-limiting and robust construction also lower maintenance frequency and downtime, yielding a favorable return on investment in mission-critical applications.
