Technical FAQs 4

How do arc flash relays work?

All Arc flash relays can connect with remote light sensors to detect arc flashes quickly and send a trip signal to interrupt power. They can be used for stand-alone devices or embedded in complex switchgear layouts. Our arc flash relays are trusted for workplace safety by B2B buyers worldwide.

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?

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.

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.
