Basic Features and Where to Buy

company amps electric range

Since 1915, the Square D logo has been recognized as a leader in the electric industry. That year, the Detroit Fuse and Manufacturing Company began producing a steel safety switch with a “D” inside a square stamped on the front. After customers began asking for the Square D safety switch, the company changed its name to Square D and has produced products under that label since. While Schneider Electric purchased the Square D company in 1991, the company continues to operate as a subsidiary of Schneider and continues to manufacture many different electric products, including power supplies, transformers, and circuit breakers.

The Square D breaker has for many years been one of the mainstays of the company, and they continue to produce a wide variety of circuit breakers. These devices are designed to protect electric devices from a current surge, and Square D breakers are available for homes, businesses, industrial settings, and motors. All of their breakers comply with the standards of the National Electric Code and are tested for safety. When you are looking at each model, you can discern most of the important information you need to know from the model number of the breaker. The model number lists, in order, the frame type, the interrupt, the number of poles, the voltage, the amps, and any necessary suffix. For example, the HJL36030M breaker has an H frame type, a J interrupting level, 3 poles, 600 volts, and 30 amps, with a molded case switch.

Those who are looking for a Square D breaker for their home will be most interested in the Miniature Circuit Breakers. The Homeline Circuit Breaker series in particular would be a good option for a circuit breaker in the home. These breakers are available in models that range from 15 to 225 amps and feature the Square D Qwik Open feature. This feature equips the breakers with a 1/60th of a second trip reaction. Another popular and flexible line of Square D breakers is the Molded Case Circuit Breaker line. These breakers range from 15 to 3000 amps, and are often used in UL 67 individual enclosures and panel boards and UL 891 switchboards. Most of the breakers in this line can be used in larger buildings, offices, and some industrial settings. Square D breakers for motors are available in a range of 1.5 to 1200 amps, and they have an adjustable trip range that goes up to 10,000 amps.

The best place to start when you are looking to buy a Square D breaker is the company’s website. Here, you can find all of the Square D breakers that the company currently produces. Prices on the breakers can vary quite widely. Prices for the Homeline breakers start at around $25 to $50. On the other hand, the higher end breakers for motors and industrial use can be $10,000 to $15,000 or more. You should be able to find a Square D breaker that meets your needs through the online store at the Square D website.
