Masterpact Low Arc Flash circuit breakers are designed and tuned to provide balanced protection for both overcurrent and arc flash. The breakers incorporate a blow-open design that clears faults ...

The tell-tale sound, flash of light, flames, and resulting smoke — all indications that an arc flash incident has taken place. It’s the ultimate workplace nightmare of every electrical professional — ...

An arc flash is defined as a hazardous explosion of energy from an electrical circuit, or a type of discharge that results from a low-impedance connection through air to ground or to another voltage ...

Incident energy is directly proportional to the total arcing time. Because of this, most strategies for arc flash hazard mitigation focus on faster detection and clearing of the arc flash. The two ...

GE’s Industrial Solutions business announced its ArcWatch circuit breaker communication technology. ArcWatch is the industry’s first technology to enable an electrical system design that helps to ...

Assumptions and complacency are two of safety’s worst enemies. If the following story hits uncomfortably close to home for you, it will have served its purpose. In January 1993, two employees were ...

There are several protection methods used in switchgear such as fast bus protection, backup over current protection and arc flash protection. Many companies have developed a state-of-the-art arc flash ...

Arc flash is defined as an explosive release of energy caused by an electrical arc. Typically, the arc results from either a phase-to-ground or phase-to-phase fault created by many possible events.

The test stand at Schneider's Cedar Rapids, Iowa, testing center shows a typical setup. Seven heat sensors are placed 18 in. from the copper bus bars. The sensors are configured to represent a head ...
