Eaton CHSF-300 High Speed Fuse - UL Recognized
Part Number: CHSF-300
Quick Summary
CHSF-300 high speed fuse protects electrical circuits in industrial power systems. Engineers often face nuisance tripping and slower startup times when protection devices do not respond quickly enough to fault conditions. This device carries UL Recognized and CSA Certified approvals along with RoHS compliance, signaling robust regulatory alignment and eco-friendly materials. By combining bolt-on mounting, a 500 Vac/500 Vdc rating, and a 300 A amperage with a 200 kAIC interrupt rating, it supports compact, scalable protection for control panels and drive systems. For panel builders and OEMs, this fuse offers reliable protection without sacrificing efficiency or installation simplicity, reinforcing your system’s safety posture and uptime.

Eaton Specification Sheet - CHSF-300
High speed response with 300 A rating and 200 kAIC interrupt capability delivers rapid fault clearance, minimizing arc energy and protecting downstream equipment in power distribution and motor control panels. This translates to measurable reductions in downtime and maintenance costs, while enabling tighter coordination with upstream protection devices. Bolt-on mounting and standard packaging simplify installation and retrofit projects, cutting commissioning time and reducing field wiring complexity in retrofit upgrades or new panel builds. As a non-indicating fuse, CHSF-300 keeps cost and part count down, though remote status monitoring can be added via compatible panel electronics for enhanced visibility in critical applications. RoHS compliance supports safer material usage and regulatory adherence across global footprints. UL Recognized and CSA Certified protections ensure conformity for industrial environments, providing procurement confidence for OEMs and integrators. The 500 Vac/500 Vdc voltage rating supports both AC drives and DC link protection, aligning with modern industrial architectures while preserving compact form factors.

FAQs
CHSF-300 is designed for bolt-on mounting in standard Bussmann series fuse holders and control panels. It fits typical industrial electrical protection cabinets and motor-control centers, enabling straightforward retrofit or new builds. For compatibility, verify available mounting holes, clearances, and the fuse holder’s rated busbar configuration before installation.
The CHSF-300 is rated for 300 A with an interrupt rating of 200 kAIC and supports a voltage of 500 Vac and 500 Vdc. It is a non-indicating, bolt-on fuse with RoHS compliance and UL Recognized as well as CSA Certified safety approvals, making it suitable for demanding industrial environments.
Yes. With a 500 Vdc rating, CHSF-300 can protect DC motor drives and DC link circuits up to the specified voltage. If your application operates at or near the 500 Vdc limit or experiences high inrush, ensure coordination with upstream protection and confirm the timeline of fault clearing to prevent nuisance tripping.
CHSF-300 carries UL Recognized and CSA Certified approvals, along with RoHS compliance. These certifications support regulatory compliance in North American markets, facilitate supplier qualification, and help reduce risk during procurement and installation in industrial facilities.
The high speed action reduces fault energy and equipment wear, contributing to longer downstream component life and less downtime. Its non-indicating design keeps initial costs low, while bolt-on installation minimizes service time. For visibility, integrate with remote monitoring where required to track fuse status and alert maintenance teams proactively.
