Product Overview

The HYUNDAI HiAN63 is a high-capacity air circuit breaker engineered for marine and industrial power distribution, designed in accordance with IEC standard low voltage air circuit breaker specification. Built for power system protection, short-circuit interruption & overload monitoring, the breaker withstands heavy fault current conditions, delivers stable continuous operation, and provides reliable power safety control for vessel main switchboards as well as industrial power distribution rooms.

Featuring draw-out structure, digital LSIG protection relay & high breaking capacity. Both 3-pole and 4-pole configurations are supported, adapting to limited space onboard ships and inside industrial control panels. The draw-out design allows breaker inspection and replacement without full busbar power cut, greatly reducing equipment downtime for service. Equipped with adjustable protection parameters, robust arc extinguishing chamber & position indicating mechanism, mature trip structure prevents circuit damage and protects downstream electrical loads during continuous duty.

For dependable power system protection, short-circuit interruption & overload monitoring, HiAN63 handles heavy load current in low voltage power networks. Reliable power system protection, short-circuit interruption & overload monitoring, premium contact materials provide excellent arc resistance, extending service life in harsh working environments. Practical adjustable protection parameters, robust arc extinguishing chamber & position indicating mechanism, precise electronic trip control lowers fault damage risk during long-hour operation, ensuring stable power supply under variable load conditions.

During continuous power system protection, short-circuit interruption & overload monitoring, HiAN63 is widely used for main power inlet, generator output and busbar protection, also serving factory substations and offshore power systems. Stable power system protection, short-circuit interruption & overload monitoring, mature HYUNDAI electric technology with easy spare parts replacement and convenient after-sales maintenance. Robust adjustable protection parameters, robust arc extinguishing chamber & position indicating mechanism, simplifies switchboard layout and reduces installation workload for marine retrofitting and industrial equipment overhaul projects.
