Eaton CHF230ST CH Thermal Magnetic Breaker - UL 489
Part Number: CHF230ST
Quick Summary
The Eaton CHF230ST CH thermal-magnetic circuit breaker protects 120/240V panels in light commercial and residential installations. Engineers often battle nuisance trips, unpredictable fault behavior, and crowded load centers when upgrading for higher short-circuit protection across mixed loads for data centers, small commercial warehouses, and service panels. Certified UL 489 and HACR-rated, with a robust common-trip two-pole design, 10 kAIC interrupt rating, and HACR compatibility for motors, it delivers reliable protection in diverse applications. Designed for Type CH load centers and offering optional shunt-trip, trip indication, and HACR suitability, it streamlines panel upgrades, ensures discrimination with upstream devices, and supports compliant 120/240V distribution standards.

Eaton Specification Sheet - CHF230ST
Eaton type CH circuit breaker limited warranty June 2024
Feature: Thermal-magnetic protection combines instantaneous magnetic tripping with a thermal element to differentiate overload from short circuits, delivering precise discrimination for 120/240V circuits. Business impact: this reduces nuisance trips, minimizes unplanned downtime, and extends equipment life in critical panels. Application: ideal for Type CH load centers in residential and light commercial installations where reliable, code-compliant protection and straightforward reset are essential. Feature: Two-pole construction with a 30 A rating provides coordinated protection across both legs of the 120/240V feed. Business impact: the 10 kAIC interrupt rating supports robust fault current handling, improving panel reliability and safety in commercial spaces with higher short-circuit potential. Application: ideal for service panels and load centers requiring common-trip protection and clear trip indication in quick-fault scenarios. Feature: Space-efficient CHF 3/4-inch-wide frame supports two-pole protection in compact panels. Business impact: the design reduces panel depth requirements and allows proper wire routing with standard Cu/Al sizes, saving installation time and reducing labor costs. Application: supports Type CH Load Centers and common wiring schemes, with wiring limits of two #14-10 AWG Cu/Al conductors and one #14-8 AWG for start-up and control feeds. Feature: UL 489 certification and HACR rating align with electrical codes and guidelines for motor circuits. Business impact: ensures compliance during inspections, reduces retrofit risk, and supports safer automation environments. Application: ideal for residential, light commercial, and mechanical equipment panels that demand dependable protection for motors and stationary loads. Feature: Shunt-trip option, trip indication, and Type CH compatibility streamline installation and future-proof panel upgrades. Business impact: enables remote or safety-interlocked shutdowns, improves fault response, and provides clear diagnostics for maintenance teams. Application: works with Type CH Load Centers, supports 120/240V circuits, and matches Eaton’s CH family ecosystem with a limited lifetime residential warranty and 1-year commercial coverage.
