The ABB SACE F2 (F2S) is a high-capacity air circuit breaker designed to protect and control electrical distribution systems in demanding marine and industrial environments. Rated at 2500A with an operating voltage of 690V, this unit is built to handle substantial electrical loads with reliability and precision. Fitted with the SACE PR1/P electronic protection unit, it provides programmable overcurrent protection functions essential for safeguarding main and emergency switchboards, power distribution panels, and generator circuits aboard commercial and offshore vessels. Air circuit breakers of this class are a critical component in any vessel’s electrical architecture, ensuring controlled fault isolation and continuous power availability across essential onboard systems.
Key Features
✓ Rated current of 2500A at 690V AC, with a short-time withstand current (ICW) of 60 kA x 1s and ICS equal to 100% of ICU, confirming full-rated breaking performance under fault conditions.
✓ Equipped with the SACE PR1/P electronic protection unit (ref. D0587G), providing long-time, short-time, and instantaneous protection settings for precise and programmable overcurrent coordination.
✓ Suitable for integration into main switchboards, distribution panels, and generator protection circuits; compatibility with specific panel configurations subject to on-site confirmation.
✓ Designed for installation in enclosed switchgear assemblies in controlled electrical spaces; mounting orientation and enclosure requirements should be verified against the vessel’s existing switchboard design.
✓ Replacement of this breaker should be carried out with reference to the original switchboard documentation to ensure correct protection coordination and system discrimination settings are maintained.
Marine Applications
✓ Main switchboard protection and power distribution management aboard large commercial vessels, tankers, and bulk carriers.
✓ Generator incomer and bus-tie breaker applications on offshore platforms, drillships, and dynamically positioned vessels.
✓ Emergency switchboard feeder protection where high fault-current ratings and reliable discrimination are operationally critical.
✓ Heavy electrical load centres on cruise ships, RoRo ferries, and naval auxiliaries requiring robust overcurrent protection at high current ratings.
✓ Shore power connection panels and high-capacity feeder circuits on vessels with large hotel or propulsion electrical loads.
