TERASAKI TEMBREAK XS800NS

Product Overview The TERASAKI TEMBREAK XS800NS is a high-frame moulded case circuit breaker manufactured by Terasaki Electric, designed for marine and industrial low voltage power distribution protection, built to comply with IEC, JIS, CE and marine classification standards. Built for main circuit overload safeguarding, short-circuit fault interruption, power load isolation, this robust panel-mounted circuit breaker withstands salt mist, cabinet temperature fluctuation, dust and mechanical vibration, delivers stable 24/7 continuous operation, and serves as core power protection hardware for marine main switchboards, offshore power panels and heavy industrial distribution systems.

Featuring 800A frame rating, optional 3-pole or 4-pole configuration, adjustable thermal-magnetic trip unit, high-performance arc quenching chamber & mechanical status indicator window. It supports fixed, plug-in or rear connection panel mounting inside low voltage switchgear, adapting to limited installation space in ship engine control rooms and industrial power houses. The modular assembly allows separate replacement of trip units and auxiliary accessories without full power system shutdown, greatly reducing equipment downtime for service. Equipped with adjustable overload threshold, high short-circuit breaking capacity & embedded mechanical fault indication function, mature hardware structure prevents electrical interference and guarantees dependable power protection performance during continuous duty.

For dependable main circuit overload safeguarding, short-circuit fault interruption, power load isolation, TEMBREAK XS800NS continuously monitors load current of distribution circuits, automatically trips under long-time overload conditions and rapidly cuts off dangerous short-circuit fault current to protect busbars, power cables and downstream electrical equipment. Reliable main circuit overload safeguarding, short-circuit fault interruption, power load isolation, premium marine-grade insulating and conductive components provide excellent long-term operational stability, extending service life in harsh marine and industrial power cabinet working environments. Practical adjustable overload threshold, high short-circuit breaking capacity & embedded mechanical fault indication function, maintenance technicians can inspect breaker status and carry out protection testing during routine power system maintenance.

During continuous main circuit overload safeguarding, short-circuit fault interruption, power load isolation, this moulded case circuit breaker is fully compatible with Terasaki marine switchgear, auxiliary contact blocks, shunt trip coils and onboard power monitoring systems. Stable main circuit overload safeguarding, short-circuit fault interruption, power load isolation, mature Terasaki TEMBREAK MCCB technology with easy spare parts replacement and convenient after-sales maintenance. Robust adjustable overload threshold, high short-circuit breaking capacity & embedded mechanical fault indication function, simplifies switchboard layout and reduces installation workload for marine power retrofitting and low voltage distribution system overhaul projects.
