Made in the USA This Larson Electronics Power Distribution Substation converts 480 VAC three phase primary electrical current to three phase and 120V and 240V AC single phase on the secondary. This heavy duty power distribution system includes a 60 amp 3 phase fusible safety switch used at 50 amp on the main for incoming 480V three phase power. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO POWER DISTRIBUTION PANELS, TRANSFORMERS, OR SUBSTATIONS* The MPD-480-45K-125MB-120/240-C-W 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 2 foot SO cord line in, which it then steps down to 120/240 VAC with a 45KVA transformer. The power distribution system on this portable substation makes 120/240V AC single phase available for operators. Features:- 20` line in SO cable- Fusible 60-Amp 480V disconnect, fused at 50 amps- 45KVA NEMA 3R 480V to 120/240V Transformer - 125 Amp NEMA 3R, 42 circuit panel 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. The transformer is mounted on a 3/16" thick carbon steel mounting platform and the load center/distribution assembly is mounted to the standard 2" x 2" x 1/8" square carbon steel tubing frame, resulting in an extremely stable, durable, and well protected power distribution platform.
