Product FAQs

7 answers
What is the difference between the Eaton CH245 and the CHF245?

The CHF245 is the upgraded version of the standard CH245. It includes a mechanical trip flag that provides a clear visual indication when the breaker has tripped, making it easier to distinguish from a breaker that has simply been turned off.

Which load centers are compatible with the CHF245 circuit breaker?

This breaker is designed exclusively for use in Eaton and Cutler-Hammer Type CH load centers. It features a proprietary 3/4-inch per pole plug-on design that will not fit in Type BR panels or load centers from other manufacturers.

Is the Eaton CHF245 HACR rated?

Yes, this breaker is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific safety designation.

Does the CHF245 require a neutral pigtail connection?

No, this is a standard thermal-magnetic circuit breaker. It does not require a neutral pigtail because it does not provide arc-fault (AFCI) or ground-fault (GFCI) protection.

How does the common trip feature work on this 2-pole breaker?

The CHF245 features an internal common trip mechanism. If an overload or short circuit occurs on either leg of the circuit, both poles will trip simultaneously to safely disconnect all power to the 240V load.

Can I install this breaker in a Square D or Siemens panel?

No. The CHF245 has a proprietary mounting clip and footprint specific to the Eaton Type CH platform. It is not interchangeable with Square D, Siemens, or GE load centers.

What does the trip flag on the CHF245 indicate?

The mechanical trip flag provides a high-visibility alert when the breaker has tripped due to an overcurrent or short circuit event. This allows electricians and homeowners to quickly identify the tripped circuit in a crowded panel without having to test each handle.

    Product is fine but customer service is not great!

    I needed these breakers for an install - first time using the company. They said they had them in stock. Took over a week to fulfil the order and it was 11 or 12 days before I had my hands on them. Tough on my business. Then when I went return them they hit me with so many fees that I was gonna net under $30 on a $104 order. It's too bad this was my first experience with them. I'll be sure to tell my electricians and project managers to never use this company. Short sighted. They won the battle but lost the war with a potential great long term client.
