520MI5W
Overview
For demanding industrial and security applications, the Leviton 520MI5W mechanical interlock provides dependable, code-compliant power control that protects equipment and personnel. This IEC pin & sleeve mechanical interlock is engineered for 3-phase systems — supporting a 4-pole, 5-wire configuration at 20A and 347/600V — so you can confidently power critical loads for security, surveillance and monitoring installations. The IP67 watertight rating and industrial-grade construction resist harsh outdoor conditions and exposure, reducing service calls and unplanned outages.
A positive mechanical interlock prevents live mating or unmating of connectors, improving onsite safety during maintenance and lowering the risk of costly downtime. Designed to meet IEC 309-1/309-2 standards, the unit integrates easily with existing pin & sleeve infrastructure; note that the hub is sold separately (see Leviton HUB-xxx). Backed by Leviton's quality and a 2-year limited warranty, the 520MI5W is ideal for camera power distribution, access control, and other networking or monitoring power points. Order the Leviton 520MI5W to secure a durable, safe power interface for your next security or industrial project.
