Square D VH221N - 30A, 2-Pole, Fused Safety Switch

The Square D VH221N is a 30A, 2-Pole Fused Safety Switch built for industrial and commercial environments that demand safe, reliable electrical isolation. Designed to support proper lockout/tagout procedures, this switch offers dependable disconnection under load and stands up to long-term use in demanding settings.

With its 2-Pole configuration, the VH221N ensures both conductors can be isolated, providing a clear, hands-on disconnection point for maintenance and service tasks. The integrated fuse protection adds a layer of overcurrent protection, enhancing safety and reducing the risk of equipment damage during fault conditions. This combination of fuse protection and deliberate isolation helps crews work more confidently and efficiently.
