ABB's WVM011Al 3 phase voltage Monitor protects against phase loss & reversal. Over, under, & unbalanced voltages that are short cycling. 10 fault memory & status that is displayed on 6 LED readout. Switch selectable automatic, restart, delayed auto- matic restart, & manual reset. Isolated 10 A SPDT relay contacts, and approvals UL Listed plus SA. Simple Type: TBD
The WVM Series provides protection against premature equipment (motor) failure caused by voltage faults on the 3 Phase Line. The WVM’s microcontroller design provides reliable protection even if regenerated voltages are present. It does combine dependable fault sensing with a 10 fault memory and a 6 LED status dis- play. Part instrument, part control, the WVM protects your equipment when you’re not there and displays what happened when you return. The WVM is fully adjustable and includes time delays to prevent nuisance tripping, and improve the system operation. Time delays include a 0.25 to 30 s adjustable trip delay, a great, adjustable 0.25 to 64 m (in 3 ranges) restart delay, plus a unique 3 to 15 s true random start delay. The random start delay prevents voltage sags caused by simultaneous restarting of numerous motor loads after a power outage.
