Larson Electronics 300 KVA Power Distribution - 480V to 208Y/120V - (2) Primary Disconnects (1) Secondary Disconnect

Made in Texas The Larson Electronics MPD-480V.3P-300KVA-600AD.208Y-100AD.480V power distribution substation converts 480V AC three phase electrical current into three phase 208Y/120V AC. This unit provides operators the ability to safely tap into and distribute 480V AC power from a variety of sources including generators and direct grid power. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO POWER DISTRIBUTION PANELS, TRANSFORMERS, OR SUBSTATIONS* Portable Power Distribution Purpose and UseThe MPD-480V.3P-300KVA-600AD.208Y-100AD.480V portable power distribution system gives operators the ability to power their 208 volt and 120 volt equipment from a single system. On the primary side, operators connect 480 volt line-in power via a customer provided cord. On the secondary side, operators connect to an 800-amp, 208V disconnect for 208Y/120V equipment. Operation: A customer provided cord brings in 480V AC three phase power to the NEMA 3R 600-amp, 480V primary disconnect, which contains three 500-amp time delay fuses protecting the 300 KVA transformer, and passes the current to the secondary panel. A second, NEMA 3R 100-amp, 480V disconnect, which contains three 100-amp time delay fuses, is also available on the primary side for input/output connections (not connected to the transformer). The NEMA 3R 300 KVA transformer converts 480V three phase power to 208Y/120V three phase and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 800-amp, 208V three phase disconnect. This secondary disconnect contains three 800-amp time delay fuses. Protective Construction: Unlike many portable power distribution boxes made of plastic and utilizing thin gauge, low grade metals in their construction, this unit is designed for serious use and is ruggedly constructed to withstand demanding conditions and heavy duty industrial applications. The transformer and load assembly 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. This model is equipped with forklift skid pockets, locking casters, and a top located lifting eyelet which allows easy lifting with cable or chain hooks. This can be replaced for an additional cost with stainless steel, hot dip galvanized steel, or aluminum depending on the customer’s needs. Larger units are available upon request and can be equipped with skids or trailer mounted. Certification: Larson Electronics is a UL 1640 panel shop and certified to build portable power distribution systems. All units are built in accordance to NFPA 70 (National Electric Code) and certified to UL 1640. All equipment is NEMA 3R rated for indoor and outdoor use and provide a degree of protection against dirt, water, and ice. NEMA 4 and NEMA 4X equipment can be equipped upon request. Grounding: Transformer is grounded to the frame and we provide a grounding lug on the frame for the earth ground. ~Please check all motor loads for dual rated motors that will work 208 or 240.~ Applications: This power distribution system is ideal for indoor or outdoor use and applications including but not limited to, construction sites, plant maintenance, plant turnarounds, shows, exhibits, and shipyard operations. These power distribution systems are popularly used in applications where external power sources are often necessary. We also offer class rated transformers for use within explosion proof and hazardous location environments.
