Elevator Fuse Card
The Elevator/Lift Fuse card is a protection card which is used to increase the safety of the elevator cards and control panel. There are two inputs, one is 110 V AC & another one is 440 V AC. The four inputs are indicated by LEDs for visual aid in determining if there is supply at the input pins. The outputs are also of 110V AC and 440V AC and in between the inputs and outputs, fuse circuit is used. These fuses react to the amount of heat being produced by electricity passing through wires and/or components. They are used so as to protect wires and components from the extreme heat produced should there be an electrical overload or short circuit. If the fuse is blown then it is also indicated by another set of LEDs and thus the electrical connection is cut instantly thereby saving the elevator cards and control panel at the output.
