5-15kV Switchgear Features
• Two-high construction features • Compact dimensions allow installation in small spaces• Robust design and durable components increase lifespan and
decrease maintenance requirements
Myers Power Products Internal Arc Resistant Medium Voltage Air-Insulated Metal-Clad Switchgear is offered in 1200A-4000A (fan cooled) continuous current ratings. The compact enclosure features vents and fl aps to direct gases and objects away from the switchgear in the event of an arc fl ash. Arc resistant switchgear incorporates rugged 5-15kV HVF breakers that are designed and manufactured with advanced vacuum technology. They have been tested according to the latest version of ANSI standards in ISO 9001 facilities, and are continuously improved to meet the evolving demands of the market. Myers Internal Arc Resistant Medium Voltage Air-Insulated Metal-Clad Switchgear is backed by nearly 40 years of switchgear and circuit breaker manufacturing experience, and has a long record of reliable performance for hundreds of utility, industrial, and commercial customers.
