What is the ABB CM-PVS.41P?
The ABB CM-PVS.41P (1SVR740794R3300) is a multi-function monitoring relay that senses abnormally high or low voltage conditions in three-phase systems. It safeguards against both undervoltage and overvoltage situations by isolating the system when voltage drops outside specified ranges. This makes it an essential component of any automated electric safety installation, particularly in industrial and commercial applications.
Main Features
Universal Voltage Monitoring: Detects undervoltage and overvoltage on three phases and neutral.
High Supply Voltage Range: Works from 160 to 300 VAC, ideal for multiple installations.
Adjustable Settings: Adjustable delay and threshold settings enable customization to match particular application requirements.
LED Indicators: Simple-to-understand LED status indicators give instant system diagnosis.
Space-Saving DIN-Rail Mounting: Convenient to mount in panels and electrical cabinets.
