Price Cut 15 kVA Isolation Transformer 60Hz 316 SS

Hubbell HBL50AITSS is a 15 kVA, 60 Hz marine isolation transformer with a #316 stainless steel enclosure, designed for 50 amp shore power systems to help provide clean, safe onboard power and reduce stray current risk.

The Hubbell HBL50AITSS Marine Isolation Transformer is designed for marine shore power systems where onboard electrical isolation, proper wiring conditions, and stray current reduction are important. Suitable for 50 amp shore power systems, this 15 kVA transformer helps minimize the possibility of stray current entering the water while supporting safer shore power operation on the boat.

This stainless steel version is built for demanding marine environments and uses a #316 stainless steel enclosure for enhanced corrosion resistance. Hubbell’s marine isolation transformers are UL listed and CSA certified, shielded for cleaner power, vibration-resistant, and encapsulated to help seal the transformer core and coil from moisture and air.
