ABB 2000 A INSULATED CASE CIRCUIT BREAKER SACE E3S 20

Product Overview The ABB SACE E3S 20 2000A Air Circuit Breaker belongs to ABB SACE Emax series low voltage power circuit breaker, engineered for industrial power distribution and generator protection systems, designed to comply with IEC 60947-2 and UL low voltage standards. Built for overload current protection, short-circuit fault interruption & main power supply isolation, this heavy-duty breaker withstands cabinet temperature fluctuation, dust and mechanical vibration, delivers stable continuous operation, and provides reliable power protection for power plants, data centers, marine switchboards, chemical plants and large industrial distribution systems.

Featuring solid-state electronic trip unit, manual/motorized operating mechanism & optional withdrawable base. Both fixed cabinet mounting and withdrawable rack installation are supported, adapting to limited installation space inside main LV switchgear rooms and power distribution cabinets. The modular assembly allows separate replacement of trip unit or operating components without full power system shutdown, greatly reducing equipment downtime for service. Equipped with adjustable protection parameters, contact wear indication & auxiliary signal contact output, mature hardware structure prevents fault expansion and guarantees dependable power distribution protection during continuous duty.

For dependable overload current protection, short-circuit fault interruption & main power supply isolation, this ABB SACE E3S 20 breaker continuously monitors line current, trips rapidly when overload or short-circuit fault occurs and isolates the faulty section to safeguard downstream loads and electrical equipment. Reliable overload current protection, short-circuit fault interruption & main power supply isolation, premium high-current conductive components provide excellent thermal stability, extending service life in harsh industrial power working environments. Practical adjustable protection parameters, contact wear indication & auxiliary signal contact output, precise trip characteristic lowers unnecessary power outage risk during long-hour operation, ensuring stable power supply under variable heavy load conditions.

During continuous overload current protection, short-circuit fault interruption & main power supply isolation, this circuit breaker is fully compatible with industrial SCADA and DCS power monitoring platforms. Stable overload current protection, short-circuit fault interruption & main power supply isolation, mature ABB SACE low voltage power distribution technology with easy spare parts replacement and convenient after-sales maintenance. Robust adjustable protection parameters, contact wear indication & auxiliary signal contact output, simplifies switchgear layout and reduces installation workload for industrial power station retrofitting and low voltage distribution system overhaul projects.
