OEL IRB4O3X3 Class 4 [36Kv] 3' X 3' Utility Rubber Blanket

The OEL IRB4O3X3 is a Class 4 insulating blanket designed for use in electrical maintenance and dielectric applications where coverage of irregular shapes is needed. Rated to 36,000 Volts AC, this blanket provides a rugged barrier for localized exposure, helping to manage dielectric risk in practical service scenarios. The orange blanket is constructed from rubber, offering a flexible, molded form that can conform to odd contours and complex geometries encountered in field and shop settings. Beaded edges enhance strength and durability, supporting repeated use in demanding environments.

Key construction features include Type II ozone-resistant rubber, which helps resist long-term aging and cracking from ozone exposure while maintaining dielectric performance. The molded design improves flexibility for wrapping and sealing around components, reducing gaps and potential exposure points. This product complies with ASTM 1048-14 and aligns with ISO 9001:2015 quality standards, supporting consistent performance and traceability in safety programs. The package is listed as each, facilitating straightforward inventory and usage planning in maintenance operations.

Practical considerations for use include verifying the blanket’s size and color for visibility and compatibility with the specific electrical tasks at hand. The 3' x 3' footprint provides a compact yet effective coverage area for typical portable or temporary dielectric barriers. For ordering and documentation, the part number IRB4O3X3 and the material specification (Rubber) are confirmed by the supplier data. A spec sheet is available for detailed technical review to support proper selection and maintenance planning.
