Even though the function of single phase and three phase relays are quite similar, their applications can vary significantly. This is primarily due to the characteristics of three phase power circuits ...

Three phase monitoring relays protect motors from severe damage that can result from loss of a phase, phase imbalance, or phase reversal. The units can protect motors used in a wide range of ...

AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...

Generally speaking, three-phase motors are less troublesome than single-phase motors, having no starting relays or capacitors to deal with. All three-phase units are high-starting-torque motors and ...

Compact and powerful, the test set provides functions needed for almost all types of single-phase protection now available on the market. Features include: Relay Testing USB interface Voltage output ...
