Eaton Specification Sheet - CHSF-175
Feature → Business Impact → Application: The CHSF-175 delivers a 175 A amperage rating with a 200 kAIC interrupt capacity, enabling rapid fault clearance that minimizes equipment damage and downtime across heavy loads in motor drives and switchgear. This improves system reliability and reduces warranty exposure, particularly in high-energy feeders and critical power paths common to process industries. Application: ideal for industrial power distribution, feeders, and panelboards where fast isolation is required to prevent arc-flash energy transfer and to maintain uptime. Feature → Business Impact → Application: The voltage rating of 500 Vac / 500 Vdc supports both AC and DC protection schemes, enabling cross-domain use in motor control centers, DC bus protection, and localized protection schemes without panel redesign. Application: suitable for mixed-voltage environments in plant automation. Feature → Business Impact → Application: RoHS compliance, CSA Certified, and UL Recognized marks provide regulatory certainty and vendor alignment, reducing procurement risk and accelerating compliance paperwork for audits. Application: ideal for aerospace-grade control panels and standard industrial installations. Feature → Business Impact → Application: Bolt-on mounting and non-indicating design simplify installation and reduce maintenance routines; once mounted, it provides reliable protection with minimal in-service adjustments. Application: fast retrofit in existing assemblies and new builds, enabling easier stocking as part of the Eaton Bussmann series family. Feature → Business Impact → Application: Standard packaging and compatibility with Bussmann catalogs streamline parts management, reducing spares inventory and service lead times. Application: reduces total cost of ownership for maintenance teams and OEMs.

FAQs
CHSF-175 uses a bolt-on mounting method designed for straightforward panel mounting. Begin by disconnecting power, align the fuse with the mounting holes, and tighten to the manufacturer’s torque specification to prevent loosening under vibration. Verify electrical clearance and that the fuse sits flush against the bus bar to ensure proper contact and safe operation.
The CHSF-175 is rated for 175 A with an interrupt rating of 200 kAIC, suitable for high-energy fault protection. It supports 500 Vac and 500 Vdc, enabling both AC and DC circuit protection. Non-indicating in normal operation, it relies on external fault indication mechanisms for status checks while delivering fast fault interruption.
Yes. The CHSF-175’s bolt-on mounting, high interrupt rating, and 500 Vac/500 Vdc capability make it suitable for motor drives and switchgear protection in MCCs. Its RoHS compliance and UL/CSA certifications help satisfy regulatory requirements, while its fast-acting design minimizes arc energy and safeguards critical motor circuits.
CHSF-175 carries CSA Certified and UL Recognized marks, plus RoHS compliance. These certifications confirm adherence to safety, performance, and environmental standards, simplifying qualification for regulated facilities and helping with supplier procurement requirements and external audits in many industrial sectors.
By providing rapid overcurrent interruption and reliable bolt-on installation, CHSF-175 reduces nuisance trips and equipment damage, contributing to higher uptime. Its non-indicating design lowers maintenance checks, and compatibility with Eaton Bussmann catalogs simplifies spare parts management, collectively lowering total cost of ownership over the equipment lifecycle.
