Replacement Fuse for the LIFEPAK 1000 Training Unit. Fuses protect the internal circuitry of an electronic device. If there is an electronic overload, the wire in the fuse melts and the fuse is then considered "blown". This protects the internal circuitry of the electronic device from damage due to electronic overload.
When a fuse blows, the device will not function until the fuse has been replaced. It must be replaced with the same type and watts fuse as the original. This fuse is a replacement for an original fuse in the LIFEPAK 1000 that has experienced an overload, and has rendered the trainer inoperable.
