About Heinemann


Heinemann's (CAD) Computer-Aided-Design equipment, our staff, and our production facilities are ideally suited for quick response to your custom Control Panel requirements.

In the beginning Heinemann engaged solely in the installation of electrical wiring systems. Unlike today, the equipment used by electrical installers was not readily available, so Heinemann had to make its own. Two key components, knife switches and fuse circuits, started Heinemann on the path of circuit protection and control, its field of specialization ever since.

In 1927, the company began development of an automatic protective device that could be reset rather than replaced - the circuit breaker. In 1932, Heinemann patented a radically different kind of circuit breaker, the hydraulic-magnetic breaker. The major advantage of this new circuit breaker was the elimination of heat-induced nuisance tripping, a problem with thermal-type circuit breakers on hot days or when they were located near heat generating equipment. The new magnetic circuit breaker is tripped by a solenoid, taking advantage of the overcurrent that occurs by default.

Today, Heinemann offers a wide range of OEM circuit protectors, with ratings from 0.01 to 1200 amperes. Their applications include computers, healthcare equipment, pleasure boats, and naval vessels, communications systems, electric locomotives and space vehicles.

Over the last 40 years, Heinemann has introduced many new products to the Hydraulic/Magnetic Circuit Breaker product line, extending its capability while maintaining its compact size.
