DM093KK - Hammond Power Solutions 93 kVA 3-Phase 480Y/277V Aluminum Drive Isolation Transformer

DM093KK

DM093KK is a 93 kVA 3-phase drive isolation transformer from Hammond Power Solutions designed for industrial power distribution applications.

This transformer features a 480Y/277V secondary voltage with a wye-neutral connection and an aluminum winding material. It is built with a 220°C insulation class (150°C temperature rise) suitable for demanding environments. The unit supports both floor and wall mounting options and is designed to withstand overcurrent conditions of 150% rated load for 60 seconds or 200% for 30 seconds. It operates at 60 Hz frequency and meets UL and CSA short circuit withstand requirements. The enclosure is rated for indoor/outdoor use with NEMA 3R/4/4X/12 protection, making it suitable for various installation environments.
