Larson Electronics Power Distribution Substation - 75KVA - 150A Main - 10 X 120V Outlets - 1 X 240V. Made in the USA This Larson Electronics Power Distribution Substation converts 480 VAC three phase primary electrical current to three phase 208Y AC and 120VAC single phase on the secondary. This heavy duty power distribution system includes a 100 amp 3 phase non-fusible safety switch on the main for incoming 480V three phase power. This model is designed for use for both linear (motor) and non-linear loads (lighting, computers, etc.). For that reason, we deliver 120V and 208Y on the secondary and provide a neutral. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO POWER DISTRIBUTION PANELS, TRANSFORMERS, OR SUBSTATIONS* The MPD-75K-150MP-4-208-10X120-1X60 portable power transformer substation 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 accept 480v 3-phase power via a 50 foot 4/4 SOOW cord with Hubbell Leviton 460P7-W 3 pole 4 wire 60 amp plug, which it then steps down to 120/208Y VAC with a 75KVA transformer. The power distribution system on this portable substation makes 120VAC available via ten 20 amp, 120 Volt GFCI duplex outlets and 208Y 3-phase available via one Hubbell Leviton 460R9W 60 amp 250V 3-phase, 3P 4W outlet. The load center on this unit is mounted within a NEMA 3R enclosure for protection against accidental contact, rain, dust, splashing water, and sprayed water.
