Shore Power Genset Changeover Reefer Container Power Pack 460V 60Hz Cold Ironing

Ports increasingly require reefer boxes to run on shore power while a vessel is alongside, yet shore supply is lost the moment the ship sails or a terminal feeder trips. This changeover power pack bridges both worlds: a 460V 60Hz shore inlet with phase rotation check and surge protection sits beside a Perkins diesel genset, and a single selector panel moves the reefer socket load between shore and genset without manual re-plugging. Operators cut fuel burn and emissions during cold ironing windows, then keep the boxes live on diesel the instant the cable is pulled.

• 460V / 60Hz shore inlet rated for continuous reefer socket load
• Phase sequence and under-voltage relay blocking closure on a bad shore supply
• Surge arrester and earth fault monitoring on the shore feeder
• Mechanical and electrical interlock between shore and genset contactors
• Cold ironing mode complies with terminal emissions restrictions at berth

• Auto start of the genset on shore supply loss, transfer under 12 seconds
• Auto return and cool down once shore supply is stable again
• Soft loading of the genset to avoid reefer compressor trip on transfer
• Selector switch for shore priority, genset priority or manual mode
• Annunciation panel showing shore available, genset running and load position

• Water cooled Perkins diesel engine, turbocharged, electronic governor
• Brushless alternator, IP23, Class H insulation, AVR holding voltage ±1%
• 460V / 60Hz three phase, matched to reefer machinery on the same bus
• 2000 L integral tank for extended unplugged terminal runs
• Radiator rated for 45°C ambient and high humidity coastal duty

• Stainless steel canopy with epoxy primed steel skid for coastal salt air
• Marine grade cable glands and IP54 junction boxes on the socket panel
• Socket outlets with individual MCB and residual current protection
• Canopy drip shield and louvered air path for driving rain conditions
• Anti-condensation heater on the alternator for idle periods

• One panel replaces separate shore box and generator, reducing yard cabling
• Fuel burn only when shore power is unavailable
• Low noise running within 62 dBA at 7 m for berth side operation
• Forklift pockets, four lifting lugs and compact 20ft footprint
• 15 months or 1200 running hours warranty, ISO and CE certificated
