DESCRIPTION

The 251-20X is an over/undervoltage relay designed to monitor 120/208V, 3-phase, 4-wire power systems operating from 50-500 Hz. It requires a 24 VDC Â± 15% control voltage and features screwdriver-adjustable trip points for both undervoltage (100-120V L-N) and overvoltage (120-140V L-N). A drop-out time delay can be set from 0.5 to 10 seconds, providing flexibility for various protection schemes. The unit includes one set of normally open and one set of normally closed contacts rated for 5A, all housed within a sealed steel can. This relay is ideal for protecting sensitive electronic equipment from damaging voltage conditions in three-phase power applications.
