What is arc resistant switchgear?

Unlike conventional switchgear, arc-resistant switchgear is designed with reinforced compartments that can withstand incredible pressure increases during high-energy arc faults. Arc-resistant switchgear offers a safe, proven, and cost-effective solution to the problem of arc flash events. Why do I need Arc-Resistant Switchgear?

Who makes arc-resistant metal-clad switch gear?

Eaton has been manufacturing arc-resistant metal-clad switchgear since 1990. Eaton was the first major North American manufacturer to design, test, and manufacture arc-resistant switchgear in accordance with EEMAC G14.1.

What is arc-resistant switchgear?

Because arc-resistant switchgear is specifically designed to contain and limit the damage incurred from internal arc faults, it provides the highest degree of protection to personnel, long-term savings, and a significant reduction in downtime.

How does an arc flash switchgear work?

Generally, this type of switchgear will come with flaps that open under the intense pressure of arcing energy. The flaps allow the heated gases of an arc flash and the pressure to safely vent out of the enclosure and away from the operator. When venting arc flash gases outside of the switchgear room is necessary, extra duct work is used.

What is arc quenching switchgear?

Arc Quenching Switchgear minimizes or eliminates damage to switchgear in the event of an arc fault, protecting valuable switchgear assets from arc flash damage. It is designed to reduce peak fault current by at least 25% and peak stress on upstream equipment by at least 44% when compared to a bolted fault device.

What is an arc flash?

An arc flash is an electrical explosion where energy leaves the circuit that it is contained in and travels through the air. The blast from an arc event combines voltage, heat—up to 35,000 degrees Fahrenheit—and violent concussion. Even with special PPE, those in the vicinity of an arc flash risk injury or even death.
