MP – Mechanical Products
MP was founded in 1940. In its early years, MP focused on developing innovative circuit breaker designs for the aerospace industry, which helped MP become the exclusive supplier of all flight-critical circuit breakers for the Apollo and Space Shuttle programs. In the mid-1950s, MP began developing circuit breakers for commercial applications. MP’s management team purchased the company in 1998. Today, MP remains a privately held company that continues to strengthen its product portfolio of thermal circuit protection devices by offering innovative solutions for the most demanding applications.
