Product FAQs

7 answers
What load centers are compatible with the CH220AFIT circuit breaker?

The CH220AFIT is designed exclusively for use in Eaton CH-series load centers. It is not compatible with Eaton BR-series or other manufacturers' panels.

Does the CH220AFIT require a pigtail neutral connection?

Yes, this breaker features a pigtail neutral design. The attached coiled white wire must be connected directly to the panel's neutral bus bar for the arc fault circuitry to function properly.

Can the 2-pole CH220AFIT be used on shared neutral circuits?

Yes, 2-pole AFCI breakers like the CH220AFIT are commonly used to provide arc fault protection for multi-wire branch circuits (MWBC) that share a single neutral wire across two 120V legs.

What does the red diagnostic LED on the CH220AFIT indicate?

The red LED displays a blink code indicating the cause of the most recent trip, such as 1 blink for a series arc, 2 for a parallel arc, or 4 for overvoltage. This helps electricians troubleshoot the specific fault on the branch circuit.

Why is the red LED on my CH220AFIT staying solidly illuminated without tripping?

A constantly illuminated red LED is a known cosmetic firmware variation on some Eaton AFCI breakers. It is not a programmed fault code and does not indicate an unsafe condition or a loss of arc fault protection.

What is the difference between the CH220AF and the CH220AFIT?

The CH220AFIT is the updated version of the CH220AF. The IT designation indicates the inclusion of advanced diagnostic electronics, such as the LED trip indicator, to assist with troubleshooting arc faults.

Is the CH220AFIT rated for HVAC equipment?

Yes, Eaton CH molded case circuit breakers are HACR rated, making this 20A 2-pole breaker suitable for heating, air conditioning, and refrigeration applications that require arc fault protection.

    Got a great refurbished breaker - saved a $6500 Service Replacement

    When our main breaker frizzed out, the option we were presented with was replacing the entire panel and service due to the type and part - no longer produced for replacement parts. It would be a $6500 replacement.

    We'll likely have to do it at some point but, for now, the replacement breaker we were able to source from Superbreakers (with a $25 warranty) was $5900 less expensive. installation ran a few hundred dollars and the tech said the part looked to be in excellent condition and was prepped for install as he would have hoped.

    Very thankful for SuperBreakers!
