Marsh Bellofram has achieved hazardous-area certifications for its UPA-130 series universal voltage alert, which is suitable for use in circuit-breaker disconnects and with high-energy panels.

The universal voltage alert – now certified to Class 1, Division 2, HAZ LOC, Groups A, B, C and D – is designed to reduce the risk of electric arc flash by pre-verifying the electrical isolation from outside of a control panel before it is re-verified with a meter.

It operates over a standard range of 40VAC to 750VAC (30VDC to 1,000VDC) line to line or ground to ground, is phase insensitive and offers high surge immunity protection.

When hardwired to the load side of a circuit breaker or main disconnects, the UPA-130 series flashes upon detection of hazardous AC and DC voltage in any individual phase.

After disconnecting power to an enclosure, electricians can pre-verify voltage isolation while an enclosure door is still safely closed.

The compact, eight-detector UPA-130 series offers a potted construction with 6ft leads and is designed to fit a 30mm knockout.

Its design includes redundant circuitry and the incorporation of long-life display panel light-emitting diodes (LEDs) for extended use, with components housed in Nema 4X, 12 and 13 electrical enclosures.

The UPA-130 series universal voltage alert is said to be a reliable safety tool for the pre-verification of the presence or absence of residual electrical power or charges or as a zero-energy indicator, both before or during mechanical lock-out/tag-out (LOTO) procedures.

It can also be used to enhance NFPA 70E and OSHA regulatory compliance standards.

The UPA-130 series is also ideal for use in applications such as circuit-breaker disconnects, as well as with NFPA 70e Category III and IV high-energy panels or as an added electrical safety tool on other types of frequently accessed electrical panels.

In addition to its hazardous-area certifications, the UPA-130 is also compliant with CatIII and CatIV standards and is CE marked and UL approved in both the US and Canada.
