Larson Electronics 75 KVA Power Distribution - 240V to 480V 3PH - (2) 480V Meltric Connectors

Made in Texas The Larson Electronics MPD-240V.3P-400A-75KVA-480V.3P-2XDR.50A temporary power distribution substation converts three phase 240V AC electrical current into three phase 480V AC. This unit provides operators the ability to safely tap into and distribute 240V 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-240V.3P-400A-75KVA-480V.3P-2XDR.50A portable power distribution system gives operators the ability to power their 480 volt equipment from a single system. On the primary side, operators bring 240V line-in power using a customer-provided cord. On the secondary side, operators can access two meltric Dr50a 31-34247-K04 connectors for 480V equipment. All connectors are protected with weatherproof covers. Operation: A customer provided line-in cord brings 240V three phase power to the NEMA 3R 200-amp, 240V three phase primary disconnect, which contains three 200-amp time delay fuses, and passes power through to the transformer. The NEMA 3R 75 KVA transformer converts 240V to 480V three phase and passes the current to the secondary panel. The secondary side of the transformer feeds two NEMA 3R 60-amp, 480V three phase disconnects, which contains three 50-amp time delay fuses each, protecting one 480V meltric Dr50a 31-34247-K04 connector (per disconnect; total of 2 connectors on the secondary side). 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. 1/8" metal sides prevent children and unwanted personel from accessing the load center. This model is equipped with forklift skid pockets, locking polyurethane 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. Larson Electronics is a manufacturer and as such can build portable transformer systems to your specifications. Although we carry several models of power distribution transformers, we can deliver custom ordered units almost as quickly as our prebuilt units.
