DESCRIPTION:

In 1904, Cutter Manufacturing Co., located in Philadelphia, began producing circuit breakers. An industry success, this new protective device was first promoted as the Inverse Time Element breaker for the innovative oil-dashpot inverse time element on its electro-mechanical circuit breaker trip devices. In 1928, Cutter changed its company name to ITE Corp and in the 1960s, through another merger, it became the ITE Imperial Company.

ITE was an innovator in the electrical industry, creating the first stored energy low and medium voltage circuit breakers. It also was the first to create 5kV air magnetic circuit breakers. ITE was purchased by Gould in 1976. At that time the products became known as ITE Gould circuit breakers. Siemens USA purchased the product line from Gould in 1983 and it has been Siemens ever since. Because of the prestige the ITE name carried, Siemens continued to use it on the line of breakers as ITE Siemens, until a few years ago. The old ITE fuse product line was retained by Gould at the Siemens transaction. What makes ITE unique is that the company was bought and sold so many times, yet continued to manufacture front-line reliable circuit breakers and switchgear.

ITE circuit breakers, like Westinghouse and General Electric circuit breakers began major manufacturing during WWII; their circuit breakers were mounted on large pieces of slate. Those breakers were called the KA-225, KB-600, KC-1600, KD-3000 and KE-4000 circuit breakers. Early on, ITE realized that they could supply circuit breakers to other companies that would manufacture switchgear or circuit breaker cells only. ITE was the largest OEM supplier of circuit breakers to other "tin knockers" or off-brand switchgear companies. Some of these companies were Nelson Circuit breakers, Pennsylvania Power circuit breakers, and one of the larger ones, Square D circuit breakers. All of them used ITE circuit breakers installed in their own switchgear.

ITE progressed like many of their competitors during the 50's with the discovery of plastics as the best non-conductive material. Incorporating plastics into the manufacturing process, ITE began producing the K-line group of circuit breakers which lasted for about 40 years - far longer than both General Electric and Westinghouse circuit breakers. The reason for this is while K-600, K-1600, K-3000 and K-4000 were good breakers, the company was purchased by Brown Boveri Company, they were then purchased by Gould circuit breakers, and later by ABB switchgear.

Over the 30 year period ITE was being bought and sold, none of the companies came up with a better design than the K-line group of circuit breakers, and each new company just adopted them and continued to manufacture them.

The one change that did occur on the breaker was the "brain" or solid state trip unit. As transistors progressed, solid state trip units got smarter. ITE manufactured the power shield trip unit; while Brown Boveri used the Powershield for some time, they later came out with the LSS trip unit. Now ABB, who also used the Powershield and LSS, manufactures the MPC-2000, all on the K-line circuit breaker!

ITE 5KV and 15KV breakers were called the HV model of breakers. They later changed to the HK model. ITE HK circuit breakers came in 1200A - 3000A models in 5KV - 15KV. ABB CIRCUIT BREAKERS also manufactured in that line until they came out with ABB vacuum circuit breakers, utilizing many of the same parts. They called this breaker the VHK line of switchgear.

This is just a brief look into how the brand ITE aka ABB has progressed through the years. The company has switched hands many times but was not adversely affected as they were able to evolve their products with the times. Electric Control carries all ABB circuit breakers for industrial use.

Electric Control stocks complete lines of ITE/ABB circuit breakers from 1945 to the present, along with an extensive parts inventory. AC-PRO trip unit retrofit conversion kits are available for all vintages of Federal Pacific/Federal Pioneer circuit breakers. Models in stock include:
