Abstract:
A protection device for monitoring current in a power cable to an electrical device:(a) a transformer magnetically linked with said power cable connected to said electrical device, said transformer producing a voltage signal in response to the presence of a changing current within said power cable; (b) a first switch circuit providing a signal to a remotely located controller in response to said sensing of said changing current; (c) a second switch circuit sensing a signal from said remotely located controller and in response preventing said changing current from reaching said electrical device; (d) a housing enclosing said transformer, said first switch circuit, and said second switch circuit; (e) said housing including an upper surface defining a first, a second, and a third opening therein, wherein said upper surface has at least one of (a) a surface area greater than one of the sides of said housing, (b) a perimeter greater than one of the sides of said housing, and (c) opposes a planar surface if said protection device were detachably connected to said planar surface using a connection mechanism provided by said protection device; (f) a first light emitting device associated with said first opening that indicates at least one of whether said second switch circuit is at least providing one of an open circuit condition and an short circuit condition; (g) a second light emitting device associated with said second opening that indicates at least one of whether said second switch circuit is at least providing one of said open circuit condition and said short circuit condition; and (h) a third light emitting device associated with said third opening that indicates whether said second switch circuit is operational.
