Inventors:

DANIEL F. STANEK - Chicago IL, US

Assignee:

International Classification:

G08B 21/00

US Classification:

340638

Abstract:

An open fuse block is provided having a visual indicator or light assembly connected in parallel with a replaceable fuse mounted in the fuse block. When the fuse is blown, the corresponding visual indicator is illuminated to identify the blown fuse, thereby facilitating quick and easy replacement of the fuse. Since the visual indicator is connected in parallel with the fuse element, when the fuse is blown, the fuse results in an open circuit and the flow of electricity is rerouted through the visual indicator. The visual indicator is thereby illuminated and the corresponding blown fuse can be easily identified. The visual indicator or light assembly can include, for example, a neon bulb, light emitting diode, fluorescent bulb, incandescent bulb, or any other visual indicator that emits light.

LITTELFUSE, INC. - Chicago IL

International Classification:

G01R 31/07

US Classification:

324550

Abstract:

An intelligent circuit protection system and method for automating component replacement and providing information to a user or operator about a load for circuit protection. The circuit protection method includes sensing current and voltage across a fuse protecting a load; sending at least one signal indicative of the current and voltage; and using the at least one signal to determine if the load is operating normally.
