FAQs
The CHT2020CS is designed for Type CH Loadcenters, offering a plug-on, single-pole solution. It simplifies retrofit projects and new installations in residential and light commercial panels, aligning with standard US panel designs to minimize compatibility issues and wiring changes.
Power must be de-energized before installation. Mount the breaker in a Type CH Loadcenter, insert it onto the bus, and connect conductors within the #14-8 AWG Cu/Al range. Follow UL 489 guidelines and Eaton installation instructions to ensure proper torque, alignment, and clamshell seating for secure operation.
The CHT2020CS carries UL 489 listing, indicating compliance with recognized safety and performance standards for low-voltage distribution equipment. This certification ensures inspectors and integrators accept the device in code-compliant panels, streamlining approvals for residential and light commercial use.
Key specs include a 20 A amperage rating, 10 kAIC interrupt rating, single-pole configuration, and 120/240 V operation at 50-60 Hz. This combination supports standard branch circuits in CH load centers while delivering reliable overcurrent protection for typical residential and small commercial loads.
Standardizing on the CHT2020CS reduces spares diversity and simplifies stocking for Type CH ecosystems. Its UL 489 listing and 10 kAIC rating translate to lower downtime during faults, easier replacements, and predictable performance, resulting in improved maintenance efficiency and overall project cost savings.
