Eaton CL250 Circuit Breaker - UL 489 Classified
Part Number: CL250
Quick Summary
Eaton CL250 circuit breaker delivers reliable 2-pole thermal-magnetic protection for CH loadcenters in commercial and residential panels. Replacing legacy hardware can be time-consuming and risky without a precise, compatible replacement. UL 489 certified, rated for 120/240 V and 50 A with a 10 kAIC interrupt rating, this classified breaker is designed as a direct replacement for common SKUs across brands. It supports Type CH Loadcenters and copper or aluminum conductors, including #14-4 AWG, and requires two 1-inch spaces. In practice, the CL250 streamlines upgrades, reduces downtime, and ensures code-compliant protection in mixed electrical environments. Engineered by Eaton, it supports consistent maintenance, simplified stocking, and clear procurement paths for OEMs and electrical contractors.

FAQs
The CL250 is designed as a classified replacement for Type CH Loadcenters and supports Cu or Al conductors up to #14-4 AWG. It is compatible with legacy SKUs including replacements for Square D Homeline and GE THQ, and it requires two 1-inch spaces in the enclosure. Ideal for residential and light commercial panels seeking a single, standards-aligned retrofit.
Begin by confirming the enclosure requires a classified two-space CL replacement. Remove the existing breaker, verify conductor sizes (#14-4 AWG Cu/Al), and install the CL250 so that both poles switch together (common trip). Ensure UL 489 compatibility and secure the wiring per NEC guidelines. This approach minimizes downtime and maintains coordinated protection.
The CL250 is a 50 A, 120/240 V two-pole circuit breaker with a common trip and a 10 kAIC interrupt rating. It carries UL 489 certification, ensuring conformity to low-voltage protection standards and reliable performance in typical residential and light commercial service entrances.
Yes, the CL250 carries UL 489 certification for safety and performance. It comes with Eaton’s warranty terms: limited lifetime for residential use and a 1-year warranty for commercial applications, supporting long-term reliability and serviceability.
The CL250 measures 3 in x 3 in x 2 in (L x H x W) with a weight of 0.5 lb, designed to fit two spaces in CH Loadcenters. It accepts Cu/Al wiring up to #14-4 AWG, and is configured as a two-pole, common-trip device for coordinated protection in standard residential and light commercial panels.
