The ABB A185-30 is a heavy-duty AC contactor rated at 275A continuous thermal current, designed for reliable switching and control of high-power three-phase motor loads and power distribution circuits. Manufactured by ABB in Sweden, this contactor is built to perform in the demanding electrical environments found in marine engine rooms, motor control centres, and main switchboard auxiliary circuits. It covers a broad operating voltage range — 220–240V, 380–415V, and 660–690V AC — making it applicable across diverse shipboard electrical systems for pump drives, compressor starters, deck machinery controls, and general feeder switching.
Key Features
✓ Continuous thermal current rating ITH = 275A, suited to sustained high-current switching duty onboard vessels (subject to nameplate confirmation)
✓ Wide voltage band coverage: UE~ 220–240V, 380–415V, 660–690V AC — compatible with a range of shipboard distribution voltages
✓ Insulation voltage UI = 1000V~, providing a high dielectric safety margin appropriate for marine power installations
✓ AC-3 motor control duty ratings: 55kW at 220–240V, 90kW at 380–415V, 132kW at 660–690V (subject to nameplate confirmation)
✓ ABB manufacture from Sweden — a recognised standard in marine and offshore electrical systems for continuous-duty, high-cycle switching applications
