Controlled Power has manufactured 38Kv switchgear since 1982. Hundreds of 38Kv circuit breakers are in reliable operation in transit, utility, and industrial applications. The HVF 38kV breakers, including vacuum interrupters, are designed and manufactured with advanced vacuum technology and have been tested according to the latest version of ANSI Standards in ISO 9001 certified facilities.

Designed with advanced vacuum technology, the vacuum interrupters retain high and reliable switching capability and high dielectric strength with only a small contact gap. The contact resistance is not affected significantly by switching operations and remains constant with the help of the contact pressure applied.

The circuit breakers require little maintenance. In fact, only the parts subject to normal wear and aging need be serviced to ensure fully reliable operation. This involves simple jobs to be carried out by the customer's personnel, short servicing times and corresponding downtimes, and also long operation periods between services. Normal maintenance is confined to lubricating the operating mechanism. The vacuum interrupters and their supports need not be serviced.

The drawout vacuum breaker has a precision racking mechanism to assure proper alignment during the insertion operation. ANSI standard safety interlocks are provided. The circuit breaker utilizes self-aligning, direct coupling secondary disconnect blocks. The cubicle includes grounded metal shutters. Several types of optional parts such as undervoltage release, second trip coil and electrical lockout are available upon request.
Optional 40 Ka rating is available.
