PowlVac Switchgear

PowlVac Switchgear

PowlVac switchgear designs combine circuit breaker and switchgear structures that are completely designed and fabricated by Powell using the highest quality components and workmanship.

Standard Construction

Our PowlVac switchgear product combines circuit breakers and switchgear structures that are completely designed and fabricated by Powell. The highest quality components are utilized to ensure product reliability and durability. Structure and circuit breakers are designed in accordance with all applicable ANSI, NEMA, and IEEE standards.

• Available in one-high and two-high construction
• Indoor NEMA-1 or outdoor NEMA-3R designs
• 1200A through 4000A main bus ratings
• Up to 63kA maximum fault Interrupting
• UL and CSA label

Arc Resistant Construction

Ideal for use when operators work in close proximity to the switchgear, our arc-resistant circuit breakers and switchgear are designed to withstand an internal arcing fault, keep personnel safe, and minimize damage to surrounding equipment.

• 5kV to 38kV applications
• Type 1, Type 2B and Type 2C designs available
• Meets ANSI 37.20.2 and C37.20.7 design standards

Narrow Design Construction

PowlVac-ND is a space-saving alternative to Powell's standard metal-clad switchgear construction. Its smaller width and depth reduces floor space and can directly replicate the footprint of older air-magnetic switchgear.

• 26 inches in width with minimum depth of 74 inches for 5kV
• 36 inches in width with a minimum depth of 104 inches for 27kV
• Up to 50kAIC rating for narrow design construction
