The ABB E16DU-18.9 is an electronic overload relay providing motor overload and phase-failure protection in industrial and marine electrical installations. With an adjustable current setting range of 5.7–18.9A and a system voltage rating of 690V AC, it is suited to a broad range of motor-driven equipment found onboard vessels and offshore facilities. Electronic overload relays of this type are commonly installed in motor control centres (MCCs), main and auxiliary switchboards, and local control panels — protecting pumps, fans, compressors, separators, and other critical machinery. The E16DU series is part of ABB’s Business & Industrial motor protection range, designed for direct integration with compatible contactor and motor starter assemblies.
Key Features
✓ Adjustable overload current range of 5.7–18.9A, covering a wide range of motor ratings
✓ System voltage rating up to 690V AC (UI), compatible with standard marine and offshore switchboard voltages
✓ Impulse withstand voltage (UIMP) of 6kV, providing protection against voltage surges in marine electrical environments
✓ IP20 protection rating, suitable for panel-mounted and enclosed switchboard installations
✓ 50/60Hz dual-frequency operation, compatible with vessels operating across varying regional power standards
Marine Applications
Motor overload protection for seawater cooling pumps, ballast pumps, and bilge pumps in engine rooms
Protection of HVAC fans, blowers, and air handling units onboard passenger and cargo vessels
Integration into motor control centres (MCCs) for auxiliary and deck machinery circuits
Overload protection for compressors, fuel separators, and other motor-driven service equipment
Use in shore connection panels and distribution switchboards fitted with motor starter assemblies
Why Marine Engineers Choose
ABB’s E16DU series is a widely recognised standard in marine and offshore motor protection, valued for consistent trip characteristics, straightforward current adjustment, and robust performance within switchboard assemblies subject to fluctuating load and supply conditions typical of shipboard operation.
Ideal For
Merchant vessels, offshore platforms, naval vessels, cruise ships, ferries, workboats, and shore-based marine industrial facilities requiring dependable motor overload protection within MCC and switchboard installations.
