Product FAQs
7 answersWhat load centers accept the CHF215ST breaker?
This breaker is designed exclusively for Eaton and legacy Cutler-Hammer Type CH load centers. It requires two 3/4-inch spaces on the panel busbar. It cannot be installed in Eaton BR series panels or competitor load centers.
What does the ST suffix indicate on the CHF215ST catalog number?
The ST suffix designates a factory-installed 120V shunt trip. This allows the breaker to be tripped remotely via an external voltage signal, which is frequently required for emergency shutdown applications or equipment interlocks.
How is the shunt trip wired on the CHF215ST?
The breaker includes factory-installed pigtail wires for the shunt trip mechanism. These leads connect to an external 120V control circuit, such as an emergency stop button or fire alarm relay. Energizing the control circuit activates the internal solenoid, mechanically tripping the breaker.
How does the trip flag function on the CHF series?
The CHF215ST includes a mechanical trip flag that provides immediate visual confirmation when the breaker has tripped. This feature eliminates guesswork in dark or crowded panels by clearly distinguishing a fault-tripped breaker from one that has been manually switched off.
Is the CHF215ST backward compatible with older Cutler-Hammer panels?
Yes. Eaton retained the original Cutler-Hammer Type CH physical footprint and busbar connection. This breaker will fit seamlessly into older Cutler-Hammer Type CH load centers.
Can I substitute an Eaton BR breaker for this CH breaker?
No. Eaton Type CH breakers are 3/4-inch wide per pole and feature a unique plug-on clip design. Eaton Type BR breakers are 1-inch wide per pole and use a different busbar connection. They are strictly non-interchangeable.
Are the terminals on the CHF215ST rated for multiple wires?
Yes, the box lugs are rated for dual wire termination. Each pole can accept either a single 14 to 8 AWG wire or two 14 to 10 AWG wires, using copper or aluminum conductors.

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.
