ABOUT US
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.
OVER THE LAST 50 YEARS
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.
