Low-voltage switchgear

Arc quenching solutions

Arc quenching solutions featuring Eaton's arc quenching switchgear reduce incident energy to levels far lower than other arc energy reducing methods. Couple arc quenching switchgear with arc-reduction vacuum fault Interrupter transformer to further enhance protection through the secondary side of the transformer.

CONTINUOUS CURRENT

up to 6000 A

voltage class

Primary: Up to 38 kV for substations; Secondary: Up to 600 V

INTERRUPT RATING

up to 100 kA

Arc quenching switchgear prevents catastrophe at a substation

In this simulated arc flash event, see how Arc Quenching Switchgear prevents disaster after a planned maintenance outage by extinguishing a phase-to-phase arcing fault within 4 milliseconds.

Incident energy reduction

Arc Quenching switchgear detects and mitigates an arcflash in less than 4 ms
Reacts more than 10 times faster than systems that rely on a circuit breaker to clear an arc fault, such as maintenance switches, ZSI, bus differential relaying and arc detection relays. A faster clearing time results in lower incident energy
Reduces incident energy below 1.2 cal/cm² which may reduce PPE requirements*
May reduce arc flash boundaries
Does not interfere with selective coordination

_{* For 600 V systems with 100,000 A of available fault current or less at a working distance of 24”. End user to determine PPE requirements based on system, application and task.}
