TERASAKI XS800NS

Product Overview The TERASAKI XS800NS is a TemBreak series moulded case circuit breaker manufactured by Terasaki Electric, engineered for marine and industrial low voltage power distribution protection, built to comply with IEC 60947, CE and DNV marine certification standards. Built for low voltage power protection, overload current tripping, short circuit fault 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 switchboards, offshore platforms, factory power distribution cabinets and heavy industrial power systems.

Featuring 800A frame size, optional 3-pole or 4-pole configuration, adjustable electronic trip unit, arc quenching chamber & mechanical status indicator window. It supports flush or surface panel mounting inside marine and industrial switchgear, adapting to limited installation space in power distribution rooms. 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 fast break mechanism, selective protection coordination & built-in mechanical fault indication function, mature hardware structure prevents signal interference and guarantees dependable power protection performance during continuous duty.

For dependable low voltage power protection, overload current tripping, short circuit fault isolation, XS800NS continuously monitors load current, trips automatically under overload conditions and rapidly isolates short-circuit faults to safeguard cables, generators and downstream electrical equipment. Reliable low voltage power protection, overload current tripping, short circuit fault isolation, premium industrial-grade insulating and conductive components provide excellent long-term operational stability, extending service life in harsh marine and industrial power cabinet working environments. Practical fast break mechanism, selective protection coordination & built-in mechanical fault indication function, maintenance technicians can inspect breaker working status and test protection functions during routine power system maintenance.

During continuous low voltage power protection, overload current tripping, short circuit fault isolation, this moulded case circuit breaker is fully compatible with Terasaki auxiliary contacts, shunt trips and marine power distribution switchgear. Stable low voltage power protection, overload current tripping, short circuit fault isolation, mature Terasaki TemBreak MCCB technology with easy spare parts replacement and convenient after-sales maintenance. Robust fast break mechanism, selective protection coordination & built-in mechanical fault indication function, simplifies switchboard layout and reduces installation workload for marine power retrofitting and industrial low voltage system overhaul projects.
