Product Overview

UPA-100 series universal power alert reduces the risk of electrical arc flash by pre-verifying the electrical isolation from outside of a control panel. Hard wired to the circuit breaker or main disconnect, the UPA flashes whenever voltage is present. Engineered with redundant circuitry, the power alert is powered by the same voltage that it indicates. Operation: The eight-detector UPA-100 visually alerts to the presence of dangerous AC or DC (Stored Energy) potentials occurring between any combination of the four monitored input lines (L1, L2, L3, GND). Two LED indicator is assigned to each input line and are designated “+” and “-”. UL Listed under UL File Number E55826. UPA-100C UNIVERSAL POWER ALERT CAT III CAT IV.
