The ABB SACE F1 (F1S) is a high-capacity air circuit breaker rated at 2000A and 690V, paired with the SACE PR1/P electronic protection unit set to a thermal current of 2000A. As a core component within the Air Circuit Breaker category, it provides reliable overcurrent, short-circuit, and overload protection for main and sub-main power distribution boards onboard vessels. Its high interrupting capacity — with ICS equal to 100% ICU and an ICW rating of 50 kA×1s — makes it well suited to demanding marine electrical environments where fault current levels are significant and system integrity is critical.
Key Features
✓ Rated at IN = 2000A and UE = 690V, with ICW = 50 kA×1s and ICS = 100% ICU, providing robust fault current withstand and full rated breaking capacity under marine operating conditions.
✓ Supplied with the SACE PR1/P electronic protection unit (ITH: 2000A), offering configurable overcurrent and short-circuit protection functions to suit specific switchboard requirements.
✓ Designed for integration into main switchboards, emergency switchboards, and power distribution panels typical of marine and offshore electrical installations.
✓ The F1S frame is suitable for fixed or withdrawable mounting configurations in switchgear assemblies; exact installation arrangement should be confirmed against the vessel’s switchboard design documentation.
✓ Replacement of the protection unit or the complete breaker assembly should be carried out in accordance with ABB service guidelines and applicable class requirements; compatibility with existing bus arrangements should be verified prior to fitment.
Marine Applications
✓ Main switchboard and section board protection on merchant vessels, tankers, bulk carriers, and container ships where high-current distribution is required.
✓ Emergency switchboard installations requiring dependable fault isolation to maintain power to essential services under fault conditions.
✓ Offshore platforms and support vessels where power distribution systems must handle high fault levels and sustained operational loads.
✓ Feeder protection for large motor starters, transformer incomers, and bus tie applications within vessel electrical systems.
✓ Newbuild and retrofit projects on naval auxiliaries, RoPax ferries, and cruise vessels requiring high-rated air circuit breakers with electronic trip units.
Why Marine Engineers Choose
The ABB SACE F1 range is well established in marine and industrial power distribution for its combination of high breaking capacity, configurable electronic protection, and robust construction — making the F1S with SACE PR1/P a trusted choice for critical switchboard applications where reliable fault protection directly supports vessel safety and operational continuity.
Ideal For
Merchant vessels, tankers, bulk carriers, container ships, RoPax ferries, offshore support vessels, drilling units, and cruise ships requiring high-rated air circuit breaker protection within main or emergency power distribution systems.
