Eaton CHF345SW CH Thermal Magnetic Breaker - UL Listed
Part Number: CHF345SW
Quick Summary
Eaton CHF345SW is a three-pole thermal-magnetic circuit breaker for panel protection in electrical distribution. Engineers often grapple with nuisance trips and compatibility gaps when upgrading Type CH Loadcenters, especially in mixed Cu/Al feeder systems. UL Listed 489 and HACR-rated performance ensure compliance for general electrical, HVAC, and commercial applications, while a limited lifetime warranty reinforces long-term reliability. With a 45 A amperage rating and 120/240 V operating range, the CHF345SW uses plug-on mounting and a switching neutral to simplify installation in CHF loadcenters and reduce wiring errors. This combination translates into improved uptime, safer fault isolation, and predictable maintenance costs for industrial environments.

Three-pole CHF plug-on circuit breaker with common trip ensures simultaneous disconnection of all poles, enhancing safety and fault isolation. This topology reduces nuisance trips and minimizes arc flash risk in panel installations, delivering measurable reductions in unplanned downtime. The 45 A rating and 120/240 V operating range support typical motor and lighting circuits while aligning with standard CH Loadcenters for reliable, scalable distribution. Switching neutral capability addresses multi-wire branch circuits without compromising protection, simplifying neutrals management and reducing wiring complexity during upgrades. Plug-on mounting streamlines field installation, cutting commissioning time and minimizing miswiring errors. UL Listed 489 and HACR rating provide regulatory confidence for HVAC and commercial equipment, enabling easier code compliance in shared spaces and stricter maintenance regimes. Copper/Aluminum #10-1/0 wire compatibility supports versatile feeder connections, while the 10 kAIC interrupt rating ensures safe fault interruption in high-energy scenarios. A limited lifetime warranty reinforces long-term value and reduces total cost of ownership in busy electrical rooms.
