OT315TPN-A ABB 315A 3P+N Steel Enclosed Switch-Disconnector IP65

Why Choose the ABB OT315TPN-A 315A 3P+N Steel Enclosed Switch-Disconnector?

The ABB OT315TPN-A is a heavy-duty 315 A 3P+N steel enclosed switch-disconnector designed for dependable load switching and electrical isolation in industrial and commercial power distribution applications. Part of ABB product group 311019 – Metal Enclosed (Loadbreak), it combines ABB OT load-break switching technology with a robust enclosed construction.

Designed for high-current local isolation, the OT315TPN-A features a steel enclosure with IP65 protection, providing a durable solution for installations exposed to dust and water ingress. Its 3P+N arrangement allows the three phase conductors and neutral to be switched as part of the isolation function, making it particularly suitable for four-wire three-phase distribution systems.

With a rated current of 315 A, the OT315TPN-A provides a substantial isolation point for machinery, distribution equipment and other high-current electrical loads. Its enclosed, manually operated design provides clear local switching and secure isolation for maintenance and servicing applications.

Reliable Three-Phase and Neutral Isolation

The ABB OT315TPN-A provides a dependable local isolation point for high-current three-phase and neutral circuits. Its 3P+N configuration makes it suitable for applications where the neutral conductor needs to be switched alongside the three phase conductors, providing a practical isolation solution for four-wire distribution systems and connected equipment.

The IP65 steel enclosure provides robust environmental protection, while the manually operated load-break switch-disconnector gives operators a clear means of disconnecting equipment from its electrical supply. This combination makes the OT315TPN-A suitable for industrial machinery, distribution equipment and local maintenance isolation points requiring a 315 A switching capacity.
