450 KVA Pad Mount Transformer - 480V Delta Primary, 208Y/120 Wye-n Secondary - Copper, ONAN/Bell Green

Product Overview

450 KVA Pad Mount Transformer - 480V Delta Primary, 208Y/120 Wye-n Secondary - Copper, ONAN/Bell Green is a product intended for professional commercial and industrial applications.

Key Specifications

• Transformer Features: With a transformer rating of 450 KVA, the industrial transformer features a primary voltage of three-phase 480V Delta and a secondary voltage of three-phase 208Y/120 Wye-n. The unit has a primary radial feed for single installations and live-front primary connections. We also offer systems with radial feed and live front primary connections. This transformer features a 5-position tap changer with two, +/- 2.5% taps above and two, +/- 2.5% taps below to allow small changes for voltage. There are no rapid rise relays present on the system.
• Temperature Rise: This unit features 65°C temperature rise for reduced heat waste, increased reliability and longer life. At 65°C temperature rise, the transformer offers 450 KVA. The transformer meets standard efficiency requirements. The combination of low temperature rise and high efficiency makes this unit suitable for use in electrical rooms, air conditioned spaces in buildings, underground vaults and similar locations, in addition to outdoor areas.
• Insulation Fluid: This transformer features non-PCB mineral oil insulation fluid. We offer transformers with biodegradable cooling fluid, if needed.
• Gauges: The following gauges are included with the system: liquid level, temperature and pressure/vacuum gauges. Standard liquid level, temperature and pressure/vacuum gauges are analog, manual reading types. These gauges do not have auxiliary contacts.
• Fault Pressure Devices: This transformer features an automatic action fault pressure device. Fault pressure devices are used to detect high rates of pressure rise within the tank.
• Rapid Rise Relay: There are no rapid rise relays on the unit. This safety component is designed for protection when a rapid increase in tank pressure occurs. The relay is suitable for detecting sudden pressure fluctuations above predetermined safe limits.
• Surge arresters: This system does not come with high elbow surge arresters on the primary side. Designed for over-voltage and transient voltage protection, the components prevent damage caused by lightning, internal switching or voltage surges. We can offer models without high elbow surge arresters that have mounting provisions for customer-provided surge arresters.
• Load Break Switch: The transformer is equipped with a load break switch. This switch has two positions: transformer on, transformer off.
• Valves: The MT-PML-R7-3P-DE-450KVA-YT-RT-LF-A6-BM-AZ-1Z2-M1 is equipped with a pressure relief valve, fill valve and drain valve with sampler port.
• Protection Fuses: This transformer does not contain protection fuses. For units without protection fuses, up stream protection is provided. We recommend provisions for protection fuses when possible, as blown fuses may require more frequent oil changes.
