HVF38HVF 38kV Vacuum Circuit Breaker

High Reliability, Long Life

Circuit Breaker Features

38kV Switchgear Features

Low Maintenance• Robust design and rugged compo-

nents increase durability and reduce maintenance

• Back-to-back capacitor switching of 90 MVAR (28kV), far exceeding of ANSI standards

Myers Power Products HVF series vacuum circuit breakers are offered in 1200A, 2000A, 2500A, and 3000A (fan cooled) continuous current. These breakers 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 38kV breakers are backed by nearly 40 years of switchgear manufacturing expe-rience and have a long record of reliable performance for hundreds of utility, industrial, and transit customers.

• Offered in 31.5kA and 40kA interrupting ratings, allowing you to purchase only the capacity you need

• Self-aligning, self-coupling secondary disconnects ensure positive connection of relay circuits to circuit breaker trip coil

• Secondary disconnects are the most robust in the industry• Heavy-duty utility grade contacts eliminate the need for manual connection of a

plug and socket or umbilical cord• Optional indicator shows breaker position when door is closed• High speed option available

• 10 year lubrication interval• 5 year routine inspection• Service required only on parts sub-

ject to normal wear and aging

• Compact 42 inch wide enclosure• Enclosure accommodates drawout CPTs (up to 15kVA) and drawout PTs above

circuit breaker, reducing lineup length• Closed door racking available• Remote trip/close available• Electric remote racking device available• Manual or electric ground and test device options
