Eaton Specification Sheet - CHSF-400
Feature: 400 A amperage rating paired with a 200 kAIC interrupt rating. Business Impact: quickly clears fault currents in high-current circuits, reducing arc energy, equipment damage, and downtime. Application: ideal for motor drives, contactors, power transformers, and high-current feeders in OEM equipment, substations, and automation racks. This combination helps facilities meet uptime targets and maintain process continuity. Feature: 500 Vac and 500 Vdc voltage ratings. Business Impact: provides versatile protection across AC and DC networks, lowering the need for separate fuses and simplifying design, stocking, and replacement. Application: suitable for servo drives, DC link protection, welding power supplies, and general purpose protection in industrial automation. Operators appreciate predictable interrupt behavior under mixed voltage conditions. Feature: Bolt-on, non-indicating design. Business Impact: enables fast, secure installation with minimal wiring and no visual indicator, which reduces maintenance checks and replacement cycles. Application: retrofits, service life extension in crowded control panels, and installations where space is at a premium. The bolt-on method supports vibration resistance and mechanical reliability in harsh environments. Feature: RoHS compliant with CSA Certified UL Recognized. Business Impact: assures environmental compliance and safety credibility, supporting audits, insurance, and customer qualifications. Application: required for many regional and customer specifications in industrial equipment, packaging machinery, and energy systems. The CHSF-400’s certifications help procurement teams meet supplier qualification and regulatory demands while maintaining consistent protective performance. Feature: Standard packaging and CHSF family compatibility. Business Impact: reduces procurement complexity, inventory, and lead times by using a single catalog line across platforms. Application: ideal for OEMs replacing legacy fast-acting fuses and service providers stocking spare parts for automation lines. The CHSF-400 integrates with bolt-on mounting rails and commonly used electrical protection schemes, supporting fast commissioning and reliable maintenance plans.

FAQs
CHSF-400 uses a bolt-on mounting method that simplifies mechanical installation. Ensure the fuse holder accepts the CHSF-400's dimensions, tightening bolts to manufacturer torque specs to avoid vibration issues. The non-indicating design reduces inspection steps, while the 400 A rating suits high-current feeders. Verify clearance and observe safety lockout/tagout procedures during replacement or retrofit.
CHSF-400 is rated for 400 A with a 200 kAIC interrupt rating and supports 500 Vac and 500 Vdc. This combination enables fast fault clearance across both AC and DC circuits, reducing fault cascade and equipment damage. The RoHS compliance and CSA Certified UL Recognized status also simplify regulatory acceptance and supplier qualification.
Yes. The 400 A / 200 kAIC rating and 500 Vac/500 Vdc capability make CHSF-400 well-suited for motor drives, switchgear, and high-current feeders. Its bolt-on design supports retrofit projects, while the non-indicating feature minimizes maintenance checks in crowded cabinets. It’s a practical choice for equipment manufacturers seeking reliable protection and quick commissioning.
CHSF-400 carries CSA Certified and UL Recognized marks, along with RoHS compliance. These certifications signal compliance with safety and environmental standards, easing audits and supplier qualification. For global deployments, the certifications help meet regional regulatory requirements and support risk management in procurement and maintenance contracts.
The non-indicating design reduces ongoing fault indicator maintenance, while bolt-on installation speeds replacements and retrofits. With a robust 400 A rating and high interrupt capability, the fuse supports longer service intervals for critical loads. The standard CHSF family compatibility also streamlines spares management and reduces total cost of ownership.
