Eaton CHQ230CS 3/4\" Thermal Magnetic Circuit Breaker - 10 kAIC
Part Number: CHQ230CS
Quick Summary
Eaton Classified 3/4\" thermal magnetic circuit breaker protects CH Loadcenters in commercial and light-industrial panels. Replacing older QO-type breakers can disrupt common-trip coordination and create panel footprint challenges, leading to extended downtime. UL 489 certification underpins safety compliance for field installations, while the unit’s two-pole design and 120/240 V rating ensure reliable multi-wire protection. This CHQ230CS solution integrates with Type CH Loadcenters, delivering consistent protection across circuits and simplifying maintenance planning. By aligning with CH series footprints and offering a clamshell-pack packaging, it supports faster stocking, safer field replacements, and lower total cost of ownership for electrical systems in industrial environments.
