ASSEMBLED IN UK
The Terasaki Tempower 2 AR216H-R is a heavy-duty 3-pole air circuit breaker rated at a maximum of 1600A, designed to provide reliable overcurrent and short-circuit protection across high-demand marine electrical installations. Belonging to the Air Circuit Breaker category, this unit is engineered for integration into main switchboards, distribution panels, and generator protection circuits onboard vessels where sustained electrical loads and fault clearance performance are critical to operational safety.
Key Features
✓ Rated up to 1600A continuous current with a 3-pole configuration, supporting balanced three-phase marine power distribution across a voltage range of 220V to 690V AC.
✓ High short-circuit breaking capacity of 80kA at 220–440V and 55kA at 500–690V, with a short-time withstand current (ICW) of 80kA for 1 second and 55kA for 3 seconds, ensuring robust fault protection.
✓ Impulse withstand voltage (Uimp) of 12kV and insulation voltage (Ui) of 1000V, confirming suitability for demanding marine electrical environments where transient overvoltages are a concern.
✓ Compatible with 50/60Hz electrical systems and rated Category B, making it appropriate for switchboard installation in main or emergency power distribution panels subject to confirmation of panel configuration.
✓ Assembled in the UK to Terasaki’s established manufacturing standards; replacement and servicing should reference the original equipment specification to ensure correct fit and electrical coordination within the existing protection scheme.
Marine Applications
✓ Main switchboard and bus-tie protection on merchant vessels, tankers, and bulk carriers where high-current distribution demands reliable fault isolation.
✓ Generator circuit breaker duties on offshore support vessels, platform supply vessels, and dredgers operating with multiple generating sets in parallel.
✓ Feeder protection for large motor starters and essential service panels on RoPax ferries, cruise ships, and naval auxiliaries.
✓ Emergency switchboard installations where Category B performance and high short-time withstand ratings are required under class society rules.
✓ Retrofit and upgrade applications replacing legacy air circuit breakers in existing marine switchgear assemblies where current ratings and breaking capacities must be maintained or improved.
Why Marine Engineers Choose
The Terasaki Tempower 2 AR216H-R is specified by marine electrical engineers for its combination of high continuous current rating, exceptional short-circuit withstand capability, and broad voltage compatibility — qualities that make it a dependable protective device in the challenging and safety-critical environment of a ship’s electrical distribution system.
Ideal For
Merchant cargo vessels, tankers, bulk carriers, offshore support vessels, platform supply vessels, RoPax ferries, cruise ships, dredgers, and naval auxiliaries requiring heavy-duty air circuit breaker protection in main or emergency switchboard configurations.
