The safest method to bring ultra-high efficiency and scalability to power distribution for demanding, business-critical applications APC Power Distribution Modules simplify both the global deployment of a standard power distribution system and the expansion of existing APC Modular Power Distribution Unit solutions. A variety of breaker and connector options can be chosen to supply either three-phase or single-phase power to the load. Safety features of the Power Distribution Modules include a latch that disconnects the breaker from AC utility power, connectors with positive locking mechanisms, and isolation of all touch points. Built-in monitoring supplies information about the power consumption of connected devices.
