Power Distribution Substation - 25kva Transformer Substation-10C/480V. Made in the USA The Larson Electronics MGS-25K-480V3P-10C Heavy Duty Power Distribution Substation converts 480 VAC three phase electrical current to single phase 120V AC and 240V AC. This power distribution system provides operators the ability to safely tap into and distribute 480VAC power from a variety of sources including generators and direct grid power. This distribution substation is suitable for outdoor use and NEMA 3R rated. The MGS-25K-480V3P-10C portable power transformer system provides a safe and reliable way for operators in industrial settings to tap into and utilize power sources independently of the work area. This unit provides an effective power distribution system for operators performing plant turnarounds, maintenance and cleaning in hazardous areas, equipment installations and repairs, and any activities requiring an alternative to native power sources. This portable transformer is designed to operate with 480v 3ph which it then steps down to 1ph 120 VAC and 1ph 240 VAC. The power distribution system on this portable substation makes 120VAC available via 8- 20amp, 120v GFCI protected duplex receptacles and 240 VAC available via 2- 30amp, 250v, twist lock receptacles. Description: The MGS-25K-480V3P-10C portable power distribution substation converts three phase, 480 VAC electrical current to single phase 120V AC and 240V AC via a 25kva transformer (480v to 120/240v, 1ph, 60hz). 25ft of 4/O cord is included to connect the substation to a 480v 3ph primary power supply and a fused disconnect, main on/off switch connects the primary supply to the 25kva transformer. Secondary current is wired to a 120/240v, 1 phase, 125 amp load center with a 100 amp main breaker for ciruit protection. Distribution is through a branch circuit comprised of 8- 20 amp, 120v breakers and 2- 30 amp, 240v breakers.
