What does Hacr mean on a breaker?
heating, air conditioning and refrigeration equipmentHACR type –This marking indicates the circuit breaker is suitable for use with the group motor installations typically found in heating, air conditioning and refrigeration equipment.
What do the letters mean on a circuit breaker?
The first letter stands for the frame type of the breaker. If it's F, it has a rating capacity of 15 to 100 amps. Other frame types include M (300-1000 Amp), L (125-400 Amp), and K (70-250 Amp). The second letter stands for its interruption rating, or how many amperes it can take before it trips.
What does the D mean on a breaker?
According to the The Electrical Guide, Type D breakers protect devices such as transformers or welding machines — items that can tolerate higher surges of electricity than home appliances.
What is a Square D QO breaker?
Square D QOT tandem circuit breakers are manufactured so two one-pole, thermal-magnetic circuit breakers occupy only one QO pole space. They are used in applications where circuit loading is light and/or noncontinuous, as in residential applications.

How do you read circuit breaker markings?
Voltage markings for breakers with slash voltage ratings are separated by a slash — for example, 208/120V or 480/277V. Each pole of the breaker is suitable when the line-to-ground voltage does not exceed the lower voltage marking, while the higher voltage marking is the value the line-to-line voltage may not exceed.
What is Hacr rating?
HACR Rated Circuit Breaker HACR stands for Heating, Air-Conditioning, and Refrigeration breaker. HACR rated breakers open within a specified time curve, similar to a fuse, to protect group motor equipment (fans for combustion air, exhaust control, heated air handling, AC compressors, etc).
Is Hacr breaker required?
HACR type – This indicates the breaker is suitable for use with the group motor installations found in HVAC equipment. The NEC no longer has this requirement.
What is the difference between Type BC and D circuit breakers?
Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A. Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device). Type D devices are designed to trip at 10-20 times In (100-200A for a 10A device).
What is a HACR breaker?
What Is the Definition of a HACR Breaker? An HACR circuit breaker is a heating, air-conditioning and refrigerator breaker. The breaker provides overcurrent protection to combustion fans, exhaust controls, AC compressors and furnaces.
What does it mean to buy a circuit breaker?
According to Home Depot, buying a circuit breaker entails knowing a breaker's load capacity as well as its limitations and compatibility. Safety and installation requirements should be considered also. Standard circuit breakers track the electrical flow for appliances, lights and electronics.
What is a two pole breaker?
A standard two-pole HACR breaker can safeguard HVAC equipment from electrical overuse, according toBuild My Cabin. A circuit breaker is a switch that instantly stops a circuit's flow in case of an electrical overload. By responding to an overcurrent condition, circuit breakers safeguard homes from electrical shocks and fire.
Why are HACR breakers used?
HACR breakers were designed specifically for the refrigeration genre of circuits because of its ability to allow for the large inrush of current, and the extended delay on that inrush, due to the nature of motor/compressors.
Can you use a non-HACR time breaker?
That is why non HACR breakers need to be supplemented with OverCurrent protection, since it is only SCGF. Yes, most of the breakers you can by at the HO depot are HACR rated already.
Is a 15A breaker the same as a 30A breaker?
In other word a 15a and a 30 breaker are exactly the same except for the thermal calibration but mag cal. is the same. A 40 and 50a breaker have the same mag. cal.
Is UL489 HACR rated?
Now HACR is part of the standard testing procedure for UL489 breakers. All UL489 breakers are now HACR rated. Some manufacturers still print the phrase HACR for marketing purposes only, because some people want to see it in writing. There are some UL proposals to eliminate the phrase HACR from different standards.

What is AFCI in circuit breakers?
Arc-Fault Protection. Circuit breakers may also include arc-fault protection (AFCI) that, like GFCIs, also has a number of unique marking and instruction requirements. Device identification – AFCIs must also be identified appropriately.
Do you need a HACR on a circuit breaker?
The electrical industry determined that circuit breakers are considered suitable for use with such equipment without any further testing, therefore, the HACR marking is no longer required on air conditioning and refrigeration equipment or on circuit breakers for use in these applications.
