The task of opening and closing breakers and switches is known to be an interaction that could result in an arc flash event. This means that anyone operating electrical distribution equipment that has ...

Devices downstream of the main breaker will most likely be assigned a lower incident arc flash energy since arc faults are cleared by the main breaker. Is it always best to go with the highest value?

Although not all injuries or deaths caused by exposure to electricity are the result of arc flash incidents, arc flash hazards present a serious risk.

This approach provides minimal protection for anyone in the arc flash blast boundary but no added protection against mechanical malfunctions such as breaker alignment or shutter problems.

With optical arc flash protection installed, the relay operating time is essentially negligible compared to the circuit breaker operating time.

An arc flash can occur when insulation or mechanical characteristics break down, letting one or more power line phases short to the ground or to each other. The resulting short circuit produces a ...

The AF0500 Arc-Flash Relay's simple, plug-and-play installation design is ideal for retrofits in electrical equipment such as switchgear, transformers, substations, motor control centers, load ...

By following a few logical steps to develop an understanding of arc flash hazards, you can help to prevent injury to yourself and those around you.
