Larson Electronics 45 KVA Power Distribution - 480V to 208Y/120V 3PH -(6) 277/480V Receptacles -Voltage Selector Switch

Made in Texas The Larson Electronics MPD-MVSS-45KVA-2X30-2X60-2X100 power distribution substation converts 480V AC three phase electrical current into three phase 208Y/120V AC. A rotary switch allows operators to select a preferred step-down voltage (415V, 380V, 230V or 208V). 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-MVSS-45KVA-2X30-2X60-2X100 portable power distribution system gives operators the ability to power their 415 volt, 380 volt, 230 volt or 208 volt equipment from a single system. On the primary side, operators connect 480V line-in power via a customer provided cord. The transformer features a set switch to allow operators to select a preferred step-down voltage (415V, 380V, 230V or 208V) for receptacles on the power distribution system. Each tap (selectable voltage) has its own corresponding receptacle. On the secondary side, operators connect to six 277/480V pin/sleeve receptacles to power equipment that is compatible with the selected step-down voltage from the set switch. All receptacles are protected by weatherproof covers. Operation: A customer provided line-in cord brings in three phase 480V power to the NEMA 3R 60-amp, 480V primary disconnect, which contains three 60-amp time delay fuses protecting the transformer, and passes the current to the secondary panel. The NEMA 3R 45 KVA transformer converts 480V three phase power to 208Y/120V three phase and passes the current to the secondary panel. Operators can select the preferred step-down voltage to pass to the corresponding receptacles using a 3-pole rotary switch with the following step-down voltage options: 415V, 380V, 230V or 208V. The secondary side of the transformer feeds a NEMA 3R 125-amp, 480Y/277V three phase main circuit breaker panel. This secondary panel contains two 100-amp breakers protecting two 100-amp, 5100R7W, 277/480V pin/sleeve receptacles, two 60-amp breakers protecting two 60-amp, 560R7W, 277/480V pin/sleeve receptacles, and two 30-amp breakers protecting two 30-amp, 530R7W, 277/480V pin/sleeve receptacles. 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.
