The UPA Voltage Alert reduces the risk of electrical arc flash by pre-verifying the electrical isolation from outside of an electrical panel. Hard wired to the circuit breaker or main disconnect, the UPA LED's flash or illuminate (depending on model) to indicate the presence of hazardous conditions, 40-600 VAC & 30-1000 VDC, associated with stored energy.
Engineered with fully encapsulated redundant circuitry, the Voltage Alert is powered by the same voltage that it indicates.
Available in 3 configurations, the easy to install UPAs fit through standard push-button and conduit knockouts.
