Medium-Voltage, Metal-Enclosed Interrupter Switchgear - Types SIEBREAK and SIEBREAK-VCB

SIEBREAK medium-voltage metal-enclosed interrupter switchgear with door open

Siemens SIEBREAKTM and SIEBREAK-VCBTM metal-enclosed interrupter switchgear designs are
modular products available in switch and fuses configuration and switch and fixed-mounted
vacuum circuit breaker configuration respectively. Both configurations are assembled and fully
integrated both mechanically and electrically to provide medium-voltage circuit protection. All
components are fully tested to perform in accordance with Siemens' standards for reliability,
quality, and service.


SIEBREAK Description

SIEBREAK switchgear is available in both fused and unfused configurations. Supplied in the unfused configuration, short-circuit protection is not available - only load-current interruption. Supplied fused or unfused, a load-interrupter switch is different from a vacuum circuit breaker in that it will interrupt load current, but not overload or fault currents.

Fused switches are available with current-limiting or expulsion (power) fuses. Fuses extend the range of applications up to the maximum ratings of the fuse, as much as 63 kA for current-limiting fuses.

A complete product line for various distribution applications:

  • Standalone bay

  • Transformer primary

  • Lineups (i.e., main-tie-main, main feeders, automatic transfer).

A complete line of switch types:

  • Single switch

  • Duplex switch

  • Selector switch.


SIEBREAK-VCB Description

Siemens SIEBREAK-VCB metal-enclosed switch and circuit breaker combination is modular assembly consisting of a load-interrupter switch mechanism connected in series with a Siemens fixed-mounted vacuum circuit breaker to provide a safe, cost effective, reliable, and flexible solution for use in standalone, low-voltage substations transformer primary, and lineup configurations. Visible disconnect is provided by the load-interrupter switch and protection is provided by the fixed-mounted vacuum circuit breaker
