The ABB SACE F1 (F1S) is a high-performance air circuit breaker rated at 1250A and 690V, supplied complete with the SACE PR1/P electronic protection unit set to a long-time handle rating of 1250A. Designed for demanding power distribution duties, this unit provides robust overcurrent and short-circuit protection within main switchboards, distribution panels, and generator protection circuits onboard commercial and industrial vessels. As a critical component within the Air Circuit Breaker category, it safeguards essential electrical systems from fault conditions that could otherwise result in equipment damage, power loss, or safety hazards at sea.
Key Features
✓ Rated at IN = 1250A and UE = 690V with an ICW of 50kA x 1s and ICS equal to 100% ICU, confirming high short-circuit withstand and breaking capability suitable for heavy-duty marine switchgear applications.
✓ Supplied with the ABB SACE PR1/P electronic protection unit (LTH: 1250A), providing configurable long-time protection to match load and distribution requirements — additional protection functions subject to configuration.
✓ Compatible with ABB SACE F1-series switchgear installations; exact panel and system compatibility should be confirmed against the vessel’s existing switchboard drawings and ABB SACE F1 frame specifications.
✓ Suitable for installation within main switchboards and distribution boards in dry, protected electrical spaces; installation should follow ABB SACE guidelines and applicable class society requirements for the vessel.
✓ Direct replacement or spare for existing ABB SACE F1S installations, referenced under serial number MD026058 with protection unit serial D0832G — confirm frame and trip unit compatibility prior to installation.
Marine Applications
✓ Main switchboard incoming and bus-tie circuit breaker duties on merchant vessels, offshore support vessels, and platform supply vessels.
✓ Generator circuit protection within engine rooms where high fault-level withstand capability is required on 690V AC distribution systems.
✓ Feeder circuit protection for large motor loads, thrusters, or high-power auxiliaries where precise overcurrent coordination is operationally critical.
✓ Power distribution panels on RoRo ferries, bulk carriers, tankers, and containerships requiring reliable high-current switchgear with electronic protection.
✓ Retrofit or like-for-like replacement in existing ABB SACE F1-series switchgear panels during scheduled dry-dock maintenance or emergency repairs.
Why Marine Engineers Choose
Marine engineers specify the ABB SACE F1 with PR1/P protection for its proven reliability in high-current distribution duties, the flexibility of electronic overcurrent protection, and the confidence that comes with ABB’s established presence in marine-grade switchgear — making it a trusted choice when switchboard integrity and uptime are non-negotiable.
Ideal For
Merchant vessels, offshore support vessels, platform supply vessels, ferries, bulk carriers, tankers, containerships, and any commercial or industrial vessel operating 690V distribution systems requiring high-capacity air circuit breaker protection.
Technical Support
Technical support is available for this ABB SACE F1 air circuit breaker and SACE PR1/P protection unit, covering onboard installation guidance, protection unit configuration, and remote troubleshooting assistance.
