Voltage alert reduces risk of electrical arc flash
CONNECTRIC SYSTEMS UPA Voltage Alert reduces the risk of electrical arc flash by providing a visual indication of the electrical isolation from outside of an electrical panel. Hardwired to the circuit breaker or main disconnect, active or stored energy potentials (40-750 Vac & 30-1000 Vdc) occurring between any combination of the four monitored input lines (L1, L2, L3, GND) are indicated by flashing LEDs. Ground fault problems are shown too. Engineered with redundant circuitry, product is powered by the same voltage that it indicates. Available in 2 sizes, the easy to install device fits through standard 30mm push-button and conduit knockouts.
