Technical FAQs 4

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 a SELCO arc flash relay?

Circuit breakers or overcurrent protection devices alone do not provide optimal protection for your personnel and equipment. A SELCO Arc-Flash Relay rapidly detects an arc flash and sends a trip signal to interrupt power in milliseconds.

What is aq-100 arc flash protection?

AQ-100 Arc flash protection series offers a complete solution that focuses on simplicity while maintaining both flexibility and function.

How long does an arc flash protection relay take?

The AQ 100 series arc flash protection relays provide trip times of 27 ms. When combined with a fast-acting circuit breaker, a total clearing time of 5 to 8 cycles is achieved. Protection schemes can be based solely on an arc light signal or on arc light and overcurrent signals occurring simultaneously.
