DTU365 - 400A Safety Switch

DTU365 - 400A Safety Switch

When you're working with a high-capacity electrical system, the right disconnect switch matters. You need a device with the right electrical ratings, a configuration that matches your equipment, and dimensions that fit the installation space. The DTU365 Safety Switch brings those essential specifications together with a 400-amp current rating, 240V voltage rating, and three-pole configuration, making it a strong option for compatible commercial and industrial electrical applications.

Whether you're replacing an existing safety switch or planning a facility electrical upgrade, matching the equipment to the job is what matters. The DTU365 is designed to serve as a disconnecting device in an appropriately rated electrical system. Its three-pole arrangement lets you switch three conductors together, a useful feature in many three-phase electrical installations.

Material Compliance and Certifications

Selecting a safety switch involves more than checking the amperage and voltage on a specification sheet. Enclosure construction, environmental suitability, short-circuit ratings, and applicable electrical certifications all play an important role in determining whether a disconnect switch meets the requirements of a particular installation.

For the DTU365, the supplied information confirms a 400-amp current rating, 240V voltage rating, three-pole configuration, and physical dimensions. However, the available specifications do not establish the enclosure material, NEMA enclosure classification, or specific UL, CSA, or other third-party certifications.
