When it comes time to replace an old breaker in an electrical panel, problems do arise. The panel may be obsolete or not well-known, and no longer manufactured. Since breakers are not interchangeable from brand to brand, just finding a breaker to fit may be impossible. This is the case with ITE panels. In 2011, ITE breakers are not well-known, and hard to find. Luckily, ITE and compatible new and refurbished breakers are available, but they are not widely distributed.
Siemens/ITE Home Breakers
In 2011, ITE refurbished breakers are available, but not widely distributed. For example, the Relectric Supply Company stocks a variety of breakers; the Siemens/ITE type B115 is a common breaker used in many panels. It is a 120-volt breaker, with a 15 ampere rating. It is also one pole, meaning it can only be used to protect one circuit in the home.
The Asea Brown Boveri company stocks breakers compatible with ITE panels for industrial applications. These are large breakers for industrial power systems, and have a voltage rating anywhere from 200 to 600 volts. The amperage rating varies anywhere from 800 to 4,200 amps, depending on the style.
Siemens Power Breakers
Siemens also manufactures power breakers for the electrical distribution industry. For example, the type HV has a voltage capacity of 5,000 volts, with an amperage rating of either 600 or 1,200 amps. The Type HK is rated for 7,500 volts, with an amperage rating of 1,200 or 2,000 amps, depending on the rating.
