PROTECTION UNIT
LTH: 1600A
The ABB SACE F1 (F1S) is a heavy-duty Air Circuit Breaker rated at 1600A and 690V, supplied complete with the SACE PR1/P electronic protection unit set to a long-time protection threshold of 1600A. Designed for high-current power distribution and overcurrent protection, this breaker is a critical component in marine main switchboards, generator distribution panels, and bus-tie arrangements onboard ships. Its robust construction and integrated protection relay make it essential for safeguarding electrical systems against overload and short-circuit conditions in demanding marine environments.
Key Features
✓ Rated at IN = 1600A and UE = 690V, with ICW = 50 kA x 1s and ICS = 100% ICU, providing high-performance short-circuit withstand and breaking capacity as confirmed in the original product data.
✓ Supplied with the ABB SACE PR1/P electronic protection unit (LTH: 1600A), offering adjustable long-time protection for precise overcurrent management within the distribution system.
✓ Compatible with marine main switchboards, generator panels, bus-tie cubicles, and high-current distribution assemblies typical of commercial and offshore vessel electrical installations.
✓ Suitable for installation in dry switchboard enclosures; mounting configuration and panel interface are subject to confirmation based on the specific switchboard arrangement onboard.
✓ As a direct replacement component, the SACE F1 series is widely supported within the ABB SACE ecosystem, simplifying spare parts management and minimising vessel downtime during maintenance periods.
Marine Applications
✓ Main switchboard incoming and bus-tie breaker positions on cargo vessels, tankers, and bulk carriers where high-current distribution protection is required.
✓ Generator incomer protection in diesel-electric propulsion systems and conventional generator sets across a wide range of commercial vessel types.
✓ Offshore support vessels and platform supply vessels where reliable switchboard protection is critical to continuous operations and DP system integrity.
✓ Passenger ferries and cruise vessels with high electrical load demands, where 690V distribution systems require robust overcurrent protection at the switchboard level.
✓ Naval auxiliaries, dredgers, and heavy marine construction vessels utilising ABB SACE distribution equipment as part of their onboard power management architecture.
Why Marine Engineers Choose
The ABB SACE F1 with PR1/P protection unit is a trusted choice for marine electrical engineers due to ABB’s long-standing presence in marine power distribution, the availability of the SACE product ecosystem for spares and support, and the breaker’s proven performance in high-demand shipboard switchboard environments.
Ideal For
Cargo ships, tankers, bulk carriers, container vessels, offshore support vessels, passenger ferries, cruise ships, dredgers, and any commercial or industrial vessel operating ABB SACE switchboard equipment with 690V high-current distribution systems.
