## **Description** The 3AG Slo-Blo[®] fuse solves a broad range of application requirements while offering reliable performance and costeffective circuit protection. The fuse catalog number with the suffix “ID” instantly identifies itself upon opening by showing a discoloration of its glass body. Guesswork and time consuming circuit testing are eliminated. This unique design offers the same quality performance characteristics as the standard 3AG Slo-Blo[®] Fuse design. ## ~~**Agency Approvals** Li~~ |**Agency**|**Agency File Number**|**Ampere Range**| |---|---|---| |G@)|E10480|10mA - 10A**| |G.|LR 29862|10mA - 10A**/15A**| |W|E10480|10A - 30A| |**PS**
