The Hyundai HAT 16 is a heavy-duty 3-pole air circuit breaker rated at 1600A and 660V AC, designed for high-current power distribution and overcurrent protection in demanding marine electrical environments. As a core component within the Air Circuit Breaker category, it is typically installed in main switchboards, distribution panels, and generator protection circuits onboard commercial and industrial vessels. Its robust interrupting capacity and short-time current ratings make it a critical safeguard for shipboard electrical systems operating under variable load conditions.
Key Features
✓ Rated at 1600A continuous current with a system voltage of 660V AC at 50–60Hz, suitable for high-demand marine power circuits.
✓ Interrupting capacity rated at 35kA at AC 660V, rising to 50kA at 550–600V and 65kA at 220–500V, providing graded fault protection across voltage ranges.
✓ Short-time current withstand rated at 50kA for 1 second and 45kA for 3 seconds, supporting selective coordination in multi-tier switchboard configurations.
✓ GL (Germanischer Lloyd) approved for marine use, confirming compliance with recognised classification society requirements for shipboard electrical equipment.
✓ Rated for ambient temperatures up to 45℃, making it suitable for engine room and switchboard room installations where elevated temperatures are typical.
Marine Applications
✓ Main switchboard incomer and bus-tie protection on cargo vessels, tankers, and bulk carriers operating high-load electrical distribution systems.
✓ Generator circuit breaker applications where reliable fault interruption and short-time withstand capability are essential for power plant protection.
✓ Feeder protection within main and emergency distribution boards on offshore support vessels and platform supply vessels.
✓ Motor feeder circuits for large auxiliary machinery including pumps, compressors, and propulsion-related electrical drives requiring high-capacity overcurrent protection.
✓ Retrofit and replacement applications in existing Hyundai-equipped switchgear panels where OEM-compatible breaker ratings are required.
Why Marine Engineers Choose
The Hyundai HAT 16 is valued for its proven interrupting performance, GL classification approval, and robust short-time current ratings that support selective tripping coordination — reducing the risk of cascading outages in critical shipboard power systems.
Ideal For
Cargo vessels, tankers, bulk carriers, offshore support vessels, platform supply vessels, ferries, and any commercial or industrial ship requiring GL-approved high-capacity air circuit breakers in main or emergency switchboard configurations.
Technical Support
Technical support is available for the Hyundai HAT 16 air circuit breaker, covering onboard installation guidance, fault diagnosis, and remote troubleshooting assistance. Support extends to switchboard integration and breaker replacement queries to help minimise downtime at sea or in port.
