【Working Principle of SPD】FSPD140 Surge Protective Device is essential for lightning protection of electronic equipment. SPDs limit transient overvoltage entering power lines or signal transmission lines to levels within the tolerance of equipment or systems, or discharge large lightning currents to the ground, thereby protecting the equipment or system from impact and damage.
【Superior Protective Performance】Surges and voltage spikes can damage or degrade the performance of your valuable electronic equipment through telephone and power lines. Comprehensive surge protection features safeguard devices such as computers, telephones, modems, televisions, and other household electronics and appliances. FSPD140 Surge Protection Device enables electrical and telephone devices to resist lightning, operate stably, and extend their lifespan.
【Special Features of Level 2 SPD】The second-level SPD further absorbs residual surge energy passed through the surge arrester at the power supply entry point and provides excellent suppression of transient overvoltages. It protects equipment inside buildings from indirect lightning strikes and switching overvoltages. It is typically installed in distribution boxes, with the main feature of handling currents with an 8/20μs waveform.
【Product Specifications】Model Name: FSPD140. Installation Type: Indoor/Outdoor. Mounting Method: Surface/Flange/Through-hole. Rated Current: 140kA. Operating Frequency: 50/60 Hz. Operating Temperature: -40℃ to 85℃ (-40℉ to 185℉). Operating Voltage: 240/120V. Nominal Discharge Current (In): 20kA. Short-Circuit Current Rating (SCCR): 200kA. Maximum Continuous Operating Voltage (MCOV): 180V (L-N, L-G, N-G), 360V (L-L). Voltage Protection Rating (VPR): 700V (L-N, L-G, N-G), 1200V (L-L).
【Installation Requirements】Externally parallel-connected and intended to be installed adjacent to electrical equipment. Verify the rated voltage matches the distribution system before installing the SPD. All circuits connected to the SPD must use equipment grounding conductors. The design ambient temperature range for this SPD is -40℃ (-40℉) to 85℃ (185℉), with relative humidity from 0% to 95% (non-condensing). Excessive temperatures may inadvertently activate the internal thermal over-temperature protector.
