Description

Medium voltage indoor circuit breakers

SF6 indoor circuit breaker : 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.

ABB’s 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.

SF6 indoor circuit breaker 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
