Product Description

Medium voltage indoor circuit breakers
  • Vacuum and SF6 gas circuit breaker for safe and reliable electrical power distribution or generation in your application up to 46 kV, 4000 A, 63 kA.
  • Maximize output and productivity with devices that support the continuous operation of your processes, e.g. three times higher mechanical endurance than the standard.
  • Protect assets with safe and reliable devices, e.g. generator circuit-breaker type tested to the new global dual logo standard (IEC/IEEE 62271-37-013).
  • Optimize investments with compact devices and high performance, e.g. 17.5 kV/50 kA circuit breaker with 210 mm pole distance.
  • ABBs indoor circuit-breakers have been designed to serve your business needs.
  • With the wide and globally available portfolio we are able to offer you the right fit for the switching of short-circuit currents, overhead lines and cables under load and no load, transformers and generators, motors, ripple control systems and capacitors even in parallel.

IEC indoor SF6 gas-vacuum multifunction apparatus HySec

Making your solution simpler

HySec comprises the functions of three different devices: circuit breaker, line disconnector and earthing switch. It is ideal for use in medium voltage switchgear for secondary distribution.

Key benefits

  • Increased personnel safety thanks to metallic partition class and integrated interlocks
  • Robust mechanical design allowing SF6 sealed-for-life and 10,000 close-open operations , providing a long-lasting solution
  • Panel footprint reduced by more than 30 percent with respect to standard solutions due to integrated multifunctions and compact design
  • Fast and easy assembly inside the panel with only one product to be mounted and connected
  • Reduced panel material by 15 percent and assembly time by 10 percent compared with a standard solution breaker-switch

Key features

  • All-in-one circuit breaker, disconnector and earthing switch
  • Integrated interlocks to prevent unsafe operations
  • Sealed-for-life enclosure filled with SF6
  • Epoxy resin upper cover for compactness; fits 500 mm wide panels
  • Stainless steel lower cover for metallic partition panels without earthing bar
  • Integrated capacitive dividers on cable side for voltage presence indication systems
