3M 77-250-A
Product Overview
The Specialty Terminals 77-250, specifically the 7MMF-250 Adapter Disconnect (Male-Female, Non-Insulated), is designed to create separable connections between electrical components. This adapter facilitates a reusable mechanical and electrical connection, joining two male quick-disconnect tabs to a single female quick-disconnect. It is suitable for applications requiring a maximum operating temperature of 482F (250C) and a maximum current of 30 Amps. A strain relief may be required for the separable connection to prevent accidental separation.
