The ABB AF16Z-30-01-21 is a compact, electronically controlled AC/DC contactor rated at 690V UI and 30A AC-1, paired with the ABB EF19-18.9 Electronic Overload Relay providing adjustable motor protection from 5.7 to 18.9A. Together, this combination forms a complete motor starter assembly commonly used in marine electrical distribution and motor control panels across a wide range of vessel types. The wide-range coil voltage (24–60V AC/DC) makes it highly adaptable to different onboard power supply configurations, while the electronic overload relay provides precise, reliable motor protection without the drift associated with thermal-bimetal devices.
Key Features
✓ Wide coil voltage range: 24–60V AC (50/60Hz) and 20–60V DC — suitable for varied onboard supply configurations
✓ ABB EF19-18.9 electronic overload relay with adjustable setting range 5.7–18.9A for accurate motor protection
✓ Rated insulation voltage UI 690V AC and impulse withstand voltage UIMP 6kV — suitable for high-voltage marine distribution environments
✓ Compact contactor format with 3-pole main contacts (30-01: 3NO + 1NC auxiliary) for straightforward panel integration
✓ IP20 rated relay module; designed for cabinet/panel mounting in marine electrical rooms and switchboards
Marine Applications
Motor starter assemblies in main switchboards and auxiliary distribution panels
Pump motor control for bilge, ballast, fire, cooling water, and fuel transfer systems
Fan and blower motor starters in engine room ventilation and HVAC systems
Compressor motor control for air conditioning, refrigeration, and starting air systems
Deck machinery and auxiliary equipment motor protection circuits
Why Marine Engineers Choose
ABB’s AF-series contactors with EF-series electronic overload relays are a well-established combination in marine motor control due to their wide coil voltage compatibility, robust protection characteristics, and straightforward integration into existing ABB and third-party control panels — reducing downtime and simplifying spares management onboard.
Ideal For
Cargo vessels, tankers, bulk carriers, offshore supply vessels, platform support vessels, ferries, dredgers, and any commercial or industrial marine application requiring reliable motor starter and overload protection assemblies.
