The ABB SACE F1 (F1S) is a heavy-duty air circuit breaker rated at 1600A and 690V, equipped with the SACE PR1/P electronic protection unit set to a long-time threshold of 1600A. As an Air Circuit Breaker, it is engineered to provide reliable overcurrent, short-circuit, and overload protection within main and secondary power distribution switchboards. Onboard vessels, units of this type are critical to safeguarding electrical systems against fault conditions, ensuring uninterrupted power supply to essential machinery and services. Its high short-circuit withstand rating (ICW = 50 kA x 1s) and full service breaking capacity (ICS = 100% ICU) make it well suited to demanding marine electrical environments.
Key Features
✓ Rated at IN = 1600A with an operating voltage of UE = 690V and a short-circuit withstand current of ICW = 50 kA x 1s, providing robust fault protection in high-power distribution circuits.
✓ Fitted with the ABB SACE PR1/P electronic protection unit with a long-time setting of 1600A, enabling adjustable and precise overcurrent protection tailored to system demands.
✓ ICS = 100% ICU confirms full service breaking capacity is maintained, meaning the breaker can interrupt maximum rated fault currents under normal service conditions without derating.
✓ Designed for installation within enclosed main switchboards and distribution panels; suitable for fixed or draw-out mounting configurations typical of marine electrical installations.
✓ Replacement of this breaker or its PR1/P protection unit should be carried out by qualified marine electricians, with settings verified against the vessel’s approved load schedules and protection coordination studies.
Marine Applications
✓ Main switchboard incomer and bus-tie breaker duties on commercial cargo vessels, tankers, and offshore support vessels where high-current distribution protection is essential.
✓ Secondary distribution panels supplying large motor drives, thruster systems, and heavy auxiliary machinery requiring stable, coordinated overcurrent protection.
✓ Passenger vessel and ro-ro ferry power distribution systems where continuous availability of electrical supply is operationally critical.
✓ Offshore platforms and drill ships with demanding power management requirements, where high fault-level withstand capacity is a key selection criterion.
✓ Naval auxiliaries, dredgers, and specialist vessels utilising ABB SACE switchgear as part of an integrated low-voltage distribution architecture.
