3-Phase Monitor with Adjustable Trip & Restart Delays

The 22-L 3-Phase Monitor provides essential protection for industrial systems. Its adjustable trip delay, ranging from 1 to 30 seconds, allows for precise response to voltage and unbalance faults, preventing unnecessary shutdowns while ensuring critical protection. A configurable restart delay, from 1 to 500 seconds, supports controlled system re-engagement after a fault, minimizing abrupt restarts and potential stress on machinery. This unit monitors for under voltage, over voltage, and voltage unbalance, with unbalance trip settings adjustable from 2-8% conforming to NEMA standards. With auto reset functionality and robust 2X SPDT 10A output contacts, it integrates seamlessly into various control schemes. This monitor enhances operational stability, reduces downtime, and contributes to extended equipment longevity by maintaining optimal electrical conditions and offering precise fault management.
