The ABB AF09Z-30-01-21 is a compact 3-pole contactor from ABB’s AF series, combined with the EF19-2.7 electronic overload relay to form a complete motor starter and protection assembly. Rated for coil voltages of 24–60V AC (50/60Hz) and 20–60V DC, with a system voltage of up to 690V AC, this combination is widely used in marine motor control centres (MCCs), main switchboards, and auxiliary distribution panels onboard commercial and offshore vessels. It provides reliable motor switching and overcurrent protection for pumps, fans, compressors, and HVAC equipment — making it a critical component for safe and continuous vessel operations.
Key Features
✓ ABB AF09Z-30-01-21 contactor with wide-range coil: 24–60V AC (50/60Hz) and 20–60V DC, accommodating varied onboard supply conditions
✓ EF19-2.7 electronic overload relay with adjustable current range 0.8–2.7A for precise motor overcurrent protection
✓ System voltage UI: 690V AC, UIMP: 6kV — rated for standard marine distribution voltages
✓ IP20 enclosure rating (relay), compact panel-mount design suitable for space-constrained machinery room installations
✓ ABB reference 1SAX121001R1103 — direct cross-reference for procurement, planned maintenance, and spares management
Marine Applications
Motor starting and protection for seawater cooling pumps, ballast pumps, and bilge pumps
Fan and ventilation motor control in engine rooms, cargo holds, and accommodation HVAC systems
Compressor and refrigeration unit motor circuits on refrigerated cargo vessels and LNG carriers
Auxiliary motor control in main switchboards and emergency switchboards across vessel types
Direct replacement and retrofit within existing ABB motor control centres and marine automation panels
Why Marine Engineers Choose ABB AF09Z with EF19-2.7
ABB’s AF contactor series is a widely specified standard across commercial shipping, offshore platforms, and naval applications, valued for its broad coil voltage tolerance, compact footprint, and long service reliability. Pairing it with the EF19-2.7 electronic overload relay eliminates the need for a separate protection device, simplifying panel design and reducing wiring complexity — a practical advantage in the confined and demanding conditions of marine electrical installations.
Ideal For
General cargo vessels, bulk carriers, tankers, offshore supply vessels, platform supply vessels (PSVs), cruise ships, ferries, naval vessels, and shore-based marine repair workshops requiring ABB motor starter and protection spares.
