The drawer includes a retractable handle that is substantially flush with the drawer when the drawer is closed. A handle recess is located adjacent the drawer for prying the handle open with a tool. A drawer frame includes a lock opening therethrough for a lock member to prevent closing of the fuse drawer as desired. Built-in fuse rejection members are included in the main housing to prevent use of incorrect fuses with the fuseholder and an auxiliary contact actuator is provided for added features on an as needed basis.
