The indicator is a neon bulb that lights when the fuse opens. When there is no power to the panel, you will not see the indicating light. It is the same functionality of indicating touch-safe blocks. It operates the same electrically as Touch-Safe Littelfuse fuse holders such as the LPSM and LPSJ. Please see the functional schematic below for more details. LF Series Functional Schematic LF Series Functional Schematic S1 F1 Indicator OFF ON OFF 100-600 VAC/DC LF Series Block LF Series Logic S1 F1 OFF LOAD What is the leakage current of the indicator? Leakage current is dependent on the voltage and resistance of the circuit, but a 600 V circuit will typically be less than 1 mA. At what voltage will the indicator lamp operate? 80-600 VAC Which will open first if I have both an indicating fuse and fuse block? The fuse element will open first, followed by the blown fuse indicator on the fuse, followed by the blown fuse indicator on the fuse holder. However, it will all appear instantaneous to the naked eye due to how quickly these things will happen. It is important to note that the holder itself doesn’t “open” – the neon bulb on the holder simply indicates an open circuit. Do indicating holders replace the need for indicating fuses? No. The indicator light only works when power is on, which greatly helps with troubleshooting. After the circuit is de-energized and locked out, the blown fuse indicator on the fuse will still show the open fuse. The blown fuse indicator is also important for fuses that are not in a holder. This redundancy improves safety. What reliability tests were performed on these new products? Fuse block reliability testing: Insertion Extraction Force, Multiple Insertion Testing, Temperature Testing, Thermal Strength, Mechanical Strength, Short Circuit, Dielectric, Open Fuse Indication, Rejection, Repeated DIN attachment, Forced DIN removal, Mounting Torque, DIN rotation and slide Indication reliability testing: Thermal Shock, Thermal Cycling, Humidity and Temperature Conditioning, Multiple Insertions, Contact Cleaner, Indication after Over-torque, Lens Retention Do you have any field data to share?
