CH2020 - 20Amp Circuit Breaker

CH2020 - 20Amp Circuit Breaker

The CH2020 is a 20 Amp, 2-pole Type CH circuit breaker with a bolt-on mounting design and a thermal magnetic trip mechanism. It is commonly used in commercial and industrial electrical systems where a breaker with these specific ratings and mounting requirements is needed. If you're replacing an existing breaker, matching the amp rating, pole configuration, mounting style, and interrupting capacity is an important part of keeping the system consistent with its original design.

Rated 65kA at 240VAC and 14kA at 480VAC, the CH2020 is intended for applications where those fault-current ratings are required. The breaker is also HACR rated and suitable for use in compatible heating, air conditioning, and refrigeration equipment. Its non-interchangeable trip unit helps maintain the protection characteristics specified for the installation, while the bolt-on construction provides a secure connection within compatible equipment.

Many electrical systems remain in service for decades, and maintenance often comes down to finding the correct replacement part. The CH2020 is designed for use in compatible Type CH equipment and provides the form, fit, and ratings required for those applications.
