SPD Electrical Systems is the world's leading supplier of shock-hardened circuit breakers and switchgear for harsh environment applications. In addition to home grown designs, SPD Electrical Systems has worked in collaboration with commercial circuit breaker suppliers to militarize COTS products for application in combatant environments. This approach offers features such as L-3 SPD Electrical Systems’ Actron circuit breakers, which allow increased automation and reduced manning through local and remote state monitoring of circuit breaker parameters. As an OEM, SPD continues to support decades of fielded circuit breaker products through a factory-based repair and overhaul center. This facility is staffed by dedicated personnel and is supported by factory resident engineers. All overhaul and emergent repair work is performed at competitive prices.
SPD Electrical Systems, in keeping pace with emerging technologies, has developed the Power Node Control Center (PNCC®). This game changing power distribution system integrates the functionality of seamless power transfer, voltage transformation, power conversion, frequency conversion, variable speed motor controlling and power switching — all through a family of programmable power electronic building blocks. Targeted at primary distribution systems rated 450 VAC (480 VAC) / 800 Vdc, the configurations of the PNCC are highly flexible and adaptable to end user needs.
