See Applicable Codes and Laws



Line Voltage Monitor — Provides pre-start and running protection against abnormal voltage conditions on line side of voltage monitor only.



Line Current Monitor — Protects on line and load side of current transformers (CT) when used in single motor branch circuit. Current unbalance protection is effective during motor running period only. Phase failure and reversal protection is provided during both starting and running periods.
