' Product Overview '
The ETX-ISX-1P-480V-0.5KVA-277V 480V Explosion Proof Fully Potted Isolation Transformer from Larson Electronics is powerful, reliable and designed with the environment in mind. Suitable for Class I, II and III rated combustible sites, the ETX-ISX-1P-480V-0.5KVA-277V provides increased reliability, protection against critical equipment failures and an extra level of protection by isolating the power source from the connected device. This NEMA 4X rated unit features two, 3/4" NPT hubs on the enclosure. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO POWER DISTRIBUTION PANELS, TRANSFORMERS, OR SUBSTATIONS* Transformer Features: With a transformer rating of 0.5kVA (500VA), the ETX-ISX-1P-480V-0.5KVA-277V fully potted explosion proof isolation transformer is a single phase unit with a primary voltage of 480V. It also provides a secondary voltage of 277V. Featuring robust construction, this unit's cores are manufactured with non-aging, cold-rolled silicon steel laminations using state of the art technology. This unit boasts a low cost of ownership and is highly energy efficient. Lower heat emissions mean less cooling is needed as well. The transformer also features a 155°C insulation with a 115°C temperature rise. This unit is protected by a copper-free aluminum enclosure and includes a watertight gasket for a NEMA 4X rating. The explosion proof transformer is designed for Class I, Divisions 1 & 2 (Groups B,C,D); Class I, Zones 1 & 2 (Groups IIB+H2,IIA); Class II, Divisions 1 & 2 (Groups E,F,G) and Class III rated combustible sites. The NEMA 4X rating makes the unit suitable for both indoor and outdoor applications, as well as ensures protection from water, dust, moisture, dirt and external ice formation. Equipped with a bolted cover, the grey explosion proof power device is compatible with surface-mount applications. Benefits: The ETX-ISX-1P-480V-0.5KVA-277V isolation transformer offers many benefits to the consumer. Precision cut copper transformer winding material help to improve performance. The close tolerances used during manufacturing also eliminates burrs which hinder performance. Each core is specially coated to prevent the ingress of moisture and are electrically balanced to minimize axial forces during short circuit situations. This transformer provides owners with significant energy savings as well as offering environmental benefits. Higher efficiency not only extends the life of the transformer, but also turn into cost savings for owners in the form of lower energy bills and decreased cost of ownership. Safety: The ETX-ISX-1P-480V-0.5KVA-277V is an explosion proof isolation transformer which means that it provides operators with an increased level of protection against electric shock. An isolation transformer can also suppress electrical noise in sensitive devices and transfer power between two circuits which must not be connected. The ETX-ISX-1P-480V-0.5KVA-277V achieves these safety features by separating or "isolating" the powered device from the power source and insulation between the primary and secondary power sources. Hubs: The explosion proof transformer contains a total of two, 3/4" NPT hubs. One, 3/4" NPT hub is located on the east side and one, 3/4" NPT hub is located on the west side of the unit. Suggested Applications: Manufacturing, Industrial, Warehouse, Lighting Systems, Oil and Gas, Marine Sites, Textile, Food Processing, Chemical Storage, Wet areas or Locations Where Combustible Dust is Present. Larson Electronics is a manufacturer and as such can build stationary and portable transformer systems to your specifications. Although we carry several models of power distribution transformer systems, we can deliver custom ordered units almost as quickly as our prebuilt units. If this model does not meet your needs, please contact us at 1-800-369-6671 or to discuss your specific requirements.
