BECKER GLOBAL-AMERICA VACUUM CIRCUIT BREAKER

Becker Global-America

5221 Series 15KV 600A

Application

The 5221 series vaccuum breaker is designed to provide over current protection for all types of electrical feed circuits by interrupting fault current upon a trip signal. The SMC breaker may be closed by operating the manual closing crank or with an appropriate signal if equipped with optional remote closing capability. It may then be opened manually or electrically by uner voltage release or shunt trip signal options.

Specification

  • Continous current: 600 Amps
  • Interrupting current: 12 500 Amps
  • Peak Momentary current: 33 000 Amps
  • Short time: 12 500 Amps
  • Maximum voltage: 27 000 Volts
  • Basic Impulse Level: 95 000 Volts

5221 Series 15KV 1200A

Application

The 5221 series vacuum breaker is designed to provide over current protection for all types of electrical feed circuits by interrupting fault current upon a trip signal. The SMC breaker may be closed by operating the manual closing crank or with an appropriate signal if equipped with under voltage release or shunt trip signal options.

Specification

  • Continuous current: 1200 Amps
  • Interrupting current: 20 000 Amps
  • Peak Momentary current: 52 000 Amps
  • Short time: 20 000 Amps
  • Maximum voltage: 15 000 Volts
  • Basic Impulse Level: 95 000 Volts

5221 Series 27KV 600A

Application

The 5221 series vacuum breaker is designed to protectively disrupt an electrical circuit upon a trip signal. The SMC breaker may be closed by operatin the closing crank namually or with an appropriate signal if the unit posses remote closing capability. It may then be opened manually or electrically by under voltage release or shunt trip signal options.
