Eaton CHSF-125 High Speed Fuse - UL Recognized, CSA Certified
Part Number: CHSF-125
Quick Summary
The Eaton CHSF-125 high speed fuse provides rapid overcurrent protection for industrial control circuits. This design helps prevent nuisance trips and downtime by reliably clearing faults before downstream equipment is damaged. It carries UL Recognized and CSA Certified safety marks, RoHS compliance, and a 500 Vac/500 Vdc rating for modern automation environments. Non-indicating status keeps costs down in high-volume assemblies, while bolt-on mounting speeds installation and reduces panel space requirements. For systems that demand robust protection with minimal maintenance, CHSF-125 delivers consistent performance and measurable uptime gains.

FAQs
CHSF-125 installs via bolt-on mounting in standard protection panels and fuse holders. Follow Eaton’s wiring diagrams for proper terminal connections and torque specifications. Because it is non-indicating, integrate an external status signal or PLC feedback to monitor fuse health and fault events during operation.
CHSF-125 is rated for 125 A with a 200 kAIC interrupt rating and voltage ratings of 500 Vac and 500 Vdc. It uses a bolt-on mounting, is RoHS compliant, and carries UL Recognized and CSA Certified safety marks, making it suitable for North American industrial applications.
Yes, CHSF-125 supports 500 Vdc in addition to 500 Vac, making it applicable for DC power supplies and drive circuits in automation environments. When using in DC applications, ensure proper heat management and secure mounting to maintain performance and minimize contact resistance during faults.
CHSF-125 carries UL Recognized and CSA Certified marks and RoHS compliance. These certifications ease supplier qualification, support regulatory audits, and help meet internal safety and environmental standards for electrical protection in control panels, switchgear, and motor control centers.
The CHSF-125 delivers faster fault clearance with a 200 kAIC interrupt rating, reducing downtime and downstream damage. Its bolt-on installation speeds commissioning, while RoHS and safety certifications reduce regulatory risk. Over time, this translates to lower maintenance costs, improved system availability, and a stronger return on investment for control and power distribution upgrades.
