To better understand these codes or catalogs, I recommend watching Circuit Breaker Catalog Numbers Explained by Electrical Power and Control. This amperage rating may vary depending on the type of frame used. If it’s 020, it simply means that the breaker amperage is rated 20. Available in both standard pigtail and time-saving Plug-on Neutral configurations, these circuit breakers combine two state-of-the-art technologies Combination Arc Fault and.

The last three digits are the actual amp circuit breaker rating. The innovative Square D QO and Homeline Dual Function Circuit Breakers by Schneider Electric save space and installation time while meeting all code requirements.If it’s two, that means it’s rated for 120 to 240 VAC, and the rating is 277 to 280 VAC if it’s four. Six means it has a voltage rating of 277-600 VAC. The second digit refers to the voltage circuit breaker ratings.It can vary between one, two, or three, depending on the actual poles you can find on the breaker. The first digit refers to the number of poles on a breaker. After the letters, you’ll find digits.There are three possible types: L, which means both ends have lugs P, which denotes lugs for one end and F, which means the breaker has no lugs. The third letter shows the type of lug a breaker has.A means Standard Rating, C stands for Extra High Rating, H is High Rating, and I is for Current Limiting Rating. The second letter stands for its interruption rating, or how many amperes it can take before it trips.Homeline 20 Amp 2-Pole GFCI Circuit Breaker. If it’s F, it has a rating capacity of 15 to 100 amps. QO 20 Amp 2-Pole Circuit Breaker(QO220CP) Shop this Collection. The first letter stands for the frame type of the breaker.These codes may give you a little bit of confusion, but they are pretty straightforward to understand.įor example, a code like FA元6020 on some breakers, especially on Square D products, denotes the following: The frequency rating you need will vary depending on your location, so you have to check with your local electrical company if you’re unsure.īeyond this basic information, you might find further catalog codes or numbers on an MCB or Miniature Circuit Breaker and an MCCB or Moulded Case Circuit Breaker. However, America and some parts of Asia use 60 Hz. Most of the world uses 50 Hz as the standard line frequency. You may also see 110 VAC, 220 VAC, or 240 VAC printed on the unit, which simply means its voltage rating.Īnother thing you can find on a circuit breaker label is the Hz rating-this is the line frequency it can transmit. These include its kiloampere rating, like 5KA or 10KA, which indicates the maximum amps it can trip. You can also find these labels on other commercial or industrial circuit breakers, like on a two-pole breaker.īut aside from the highlighted number and logo, you can also find other combinations of digits and letters printed on a breaker. Those circuit breaker numbers mean the amp rating of a particular circuit breaker. What Do the Numbers and Letters on a Circuit Breaker Mean?Ī typical house circuit breaker you can find has a highlighted number label.
