Frequently Asked Questions
What is the purpose of semi-flush mounting?
These relays are installed using a semi-flush mounting method, wherein the relay is partially recessed into a wall or panel, leaving a portion exposed for easy maintenance and troubleshooting purposes.
What is zone selective interlocking?
Zone selective interlocking improves coordination and tripping time between protective relays in different zones of a power system, where the closest protective device to the fault gets tripped while others remain unaffected. It allows faster isolation and reduces the number of circuit breakers that need to be tripped in the event of a fault, thereby resulting in fewer power outages.
What is an arc flash?
Arc flash is a type of electrical explosion that may be caused when an electric arc forms between two conductors, releasing a tremendous amount of energy in the form of heat, light and pressure. Eaton distribution relays improve safety against such hazardous arc flashes by containing & redirecting the arc flash and destroying it completely.
