Features and Benefits

NPP - Series (special order)

The NEMA Pump Panels are provided with a motor disconnect and short circuit protection. The motor overload protection comes with two types of protection. The standard pump panel comes with the melting alloy type thermal overload or as an option, the panel can be provided with a Solid State Overload protection. The solid state overload relays are designed to protect three phase AC motors from overload, phase unbalanced and phase loss conditions. The solid state overload relay has a selectable trip; Class 10, Class 20 or Class 30.
