GE SFHA Breakers
General Electric is a multinational corporation with historical ties to inventor Thomas Edison. Today, General Electric produces a wide variety of electrical products, from home appliances to circuit breakers.
One of GE’s most popular products is the GE SFHA circuit breaker.
Circuit Breaker Markings
No matter what type of circuit breaker you decide on, whether it’s an SFHA or something else, it helps to know a little about what the markings mean.
The NEC (National Electrical Code) set the Underwriters Laboratory (UL) 489 product marking standards. UL 489 requires certain information marked in certain locations.
However, these are minimum requirements, and some manufacturers add more markings with different meanings. The safest way to ensure that you have the right breaker or part is to consult the manufacturer’s manual.
SFHA Circuit Breaker Line
The GE SFHA breakers line is one of many lines of molded case circuit breakers that General Electric makes. Their popularity with the domestic, commercial and industrial sectors characterizes these breakers. They can handle currents up to 2500 Amps.
The last three numbers of the serial number corresponds to each model’s maximum amperage information. For example, if the serial number is SFHA368T2125C, then the maximum amperage that the breaker can withstand will be 125 Amps.
Below you will find more information about the different molded case SFHA circuit breakers made by General Electric, including their sizes, maximum amperage and voltage information, as well as their physical dimensions.
SFHA368T2125C
The SFHA368T2125C circuit breaker by GE is a 125 Amps and 600 Volts rated circuit breaker. Since it is a molded case circuit breaker, it is designed with an electrochemical trip unit that protects against excess currents. As a modern molded case circuit breaker, it also uses one or a combination of different trip units to protect against thermal overloads, short circuits and ground faults. The SFHA368T2125C has three poles so that it can protect three different circuits.
SFHA36AT0200
The SFHA36AT0200 circuit breaker by GE is a 200 Amps and 600 Volts rated breaker. The SFHA36AT0200 is also a molded case circuit breaker designed with many trip units to protect against thermal overloads. It has three poles, making it suitable to protect three different circuits.
SFHA36AT2250C
The GE SFHA36AT2250C circuit breaker has a 250 Amps maximum amperage rating, 600 Volts maximum voltage rating, and a width of 4.12 inches, a depth of 3.81 inches and a height of 10.12 inches. It has an SF frame type. It is also a molded case circuit breaker with various tripping mechanisms. The trip units on the SFHA36AT2250C include long and short trip units, as well as an instantaneous trip mechanism to protect against thermal overloads. It has three poles and can protect three different circuits.
SFHA36AT2150C
The SFHA36AT2150C circuit breaker by GE has a 150 Amps maximum amperage rating, 600 Volts maximum voltage rating with the same dimensions as that of the SFHA36AT2250C. It has an SF frame type. Like all models listed before, it is also a molded case circuit breaker and consists of long and short trip units, as well as an instantaneous trip mechanism to protect against thermal overloads. It has three poles, making it suitable for three-phase circuits.
SFHA36AT2125C
GE’s SFHA36AT2125C circuit breaker has a 125 Amps maximum amperage rating and a 600 Volts maximum voltage rating. It is the same size as the SFHA36AT2150C and the SFHA36AT2250C. It is an SF frame type and is a molded case circuit breaker. Its trip units consist of a long, short and instantaneous trip mechanisms to protect against thermal overloads. It has three poles, making it suitable for three-phase circuits.
SFHA36AT0250
The SFHA36AT250 circuit breaker by GE has a 250 Amps maximum amperage rating and 600 Volts maximum voltage rating. With a width of 4.12 inches, a depth of 3.81 inches and a height of 10.12 inches, it is the same size as all prior models. It has an SF frame type and is a molded case circuit breaker. Its trip units consist of a long, short and instantaneous trip mechanisms, as well as three poles for connecting with three different circuits.
SFHA368T2125C
The SFHA368T2125C circuit breaker by GE has a 125 Amps maximum amperage rating and 600 Volts maximum voltage rating. Like other SFHA models, it is a molded case circuit breaker, meaning its trip units consists of a long, short and instantaneous trip mechanisms. It also has three poles for connecting with three different circuit systems.
Final Thoughts
The SFHA line of circuit breakers is produced by large electrical appliance manufacturer, General Electric. This line of circuit breakers all have the same physical dimensions, are triple-poled with SF frame types and have a maximum voltage rating of 600 Volts. Their maximum amperage ratings differ and can be found on the last three digits of the model’s serial number.
