When the water is rising, there is no time for a pump failure.

ABB offers a complete line of motor protection relays and controls. The SSAC brand of three phase voltage monitors covered in this article, offer cost advantages over other solutions for all installations where across the line or star delta starting is used. They can be used in conjunction with softstarters to provide improved protection since they are able to detect single phasing, phase reversal and low voltage before the pump is started.

Request your copy of the Pumping System Brochure and see the improvements available for your pumping systems.
Key Benefits:

• ABB's Low Cost Pump Protection Relays - keep pumps (an other 3 phase motors) running
• Reliable SSAC brand designs are backed by a 10 Year warranty
• Will not allow the pump to restart if 3 phase voltages are not within the acceptable range
• Phase loss protection even when regenerated voltages are present also means excellent protection from unbalanced voltages.
• Universal design works with any size pump - 1 to 1200 hp
• Universal voltage designs (200 thru 480V AC) reduce inventory, one part for all applications
• Octal Plug-in designs with industry standard base wiring replace over 100 competitive part numbers, improving operation (PLMU Series)
• Units designed for DIN rail (CM-MPS) or back panel mounting (HLMU & WVM Series)
• Miniature 2" x 2" x 1.2" modules (TVW Series) provide full protection but can be added to any existing control panel
• ETL tests prove ABB SSAC products provide superior protection
• Trip delay prevents nuisance tripping
• Restart delay prevents short cycling and allows staggered restarting of multiple motors on a common power network.

Having Unexplained Motor, Pump or Compressor Failures?

These interactive animations show the possible cause of these costly events.

Animations show why motor windings overheat and prematurely fail when adverse three phase voltages are present. Motor health can be compromised when the voltage at the terminal lugs is outside the specification window. See what happens to the winding’s temperature when subjected to: Phase Loss, Under Voltage and Unbalanced Voltages. Animations include meters that display reference voltages during fault events.
