Power alert available with low profile mounting

03 March 2009

The Universal Power Alert (UPA) device from Marsh Bellofram Europe provides a visual external indication of live power or stored energy conditions existing within an electrical enclosure. This inexpensive device helps prevent arc flash and possible electrocution, by pre-verifying that full electrical isolation conditions exist before the access door or cover is opened to any enclosure containing electrical power devices.

The permanently installed UPA 130 unit supplements conventional voltmeter testing and helps maintain compliance with the National Fire Protection Association NFPA 70E safety standards. These power alerts are suitable for use on single and three phase power supplies.

The UPA 130 uses standard pushbutton or conduit knockouts for mounting and is permanently wired to the circuit breaker or otherwise potentially hazardous live power supply which is indicated with flashing LED’s. A low profile mounting option is also available which is used with an external protective bezel. This reduces the front-of-panel projection, providing greater protection against possible vandal attack or accidental impact damage. The product is also fully encapsulated and provided with redundant circuitry to ensure that the primary electronic functions of power source identification and indication are maintained.
