The ABB A145-30-22 (part number A145-30-22-85, catalogue reference 1SFL471001R8522) is a heavy-duty low-voltage power contactor from ABB’s A-line series, manufactured in Sweden. Rated at ITH 250A and UI 1000V AC-1, it is designed for high-current switching applications in industrial and marine electrical systems. Onboard vessels, contactors of this class are critical components in main switchboards, motor control centres, distribution panels, and power management systems where reliable, high-cycle switching under load is essential to safe and continuous operation.
Key Features
✓ High thermal current rating of 250A (ITH) and AC-1 load rating of 250A, suitable for resistive and mildly inductive load switching
✓ Rated insulation voltage of 1000V AC, providing margin for demanding marine electrical environments
✓ ABB A-line frame construction — a proven contactor family widely used across industrial and marine power applications globally
✓ Auxiliary contact configuration per A145-30-22 designation, supporting control circuit integration and interlocking schemes
✓ Manufactured in Sweden to ABB production standards; catalogue number 1SFL471001R8522 ensures traceable sourcing and spares compatibility
Marine Applications
Main switchboard and distribution panel power switching on commercial vessels and offshore units
Motor control centres (MCC) for pumps, compressors, fans, and auxiliary machinery
Power management and load-shedding systems requiring reliable, high-current contactors
Thruster and propulsion auxiliary panel switching where high-cycle endurance is required
Shore power changeover and bus-tie panel assemblies on larger vessels and FPSOs
Why Marine Engineers Choose
ABB A-line contactors are a long-established standard in marine and offshore electrical installations. The A145-30-22 offers a robust, high-current switching solution with a traceable part number, broad coil voltage availability, and a proven service record in demanding shipboard environments — reducing unplanned downtime and simplifying OEM replacement.
Ideal For
Cargo vessels, tankers, bulk carriers, offshore supply vessels, FPSOs, drillships, cruise ships, ferries, naval auxiliaries, and industrial marine installations requiring heavy-duty low-voltage power switching components.
Technical Support & Compliance
We provide complete solutions including remote technical troubleshooting, onboard support and installation assistance, testing and commissioning, repair and overhaul, retrofit and upgrade support, and full system integration guidance. To confirm compatibility with your installation, please share nameplate photographs, full part numbers and catalogue references, single-line or wiring drawings, switchboard or MCC model and version details, and vessel name or IMO number where applicable. Suitability for specific control voltage, auxiliary contact configuration, or system requirements is subject to confirmation based on the above information.
