FSPD140 Level 2 Whole House Surge Protection Device - 140,000A Rated for EV Charging, Storm Zones, and Grid Surges, Upgraded Replacement for Siemens FS140, Includes Wiring & Locknut

Surge Current Capacity - The FSPD140 offers a significant surge protection capacity of 140,000 Amps, making it ideal for areas with frequent and severe storms. As a Type 2 SPD, it provides 140kA of surge current protection per phase
Multi-Layer Protection - Built-in MOVs instantly detect voltage spikes and absorb excess energy, preventing it from reaching sensitive electronics and appliances. When voltage exceeds normal operating levels, the MOVs switch from a high-resistance state to a low-resistance state, safely redirecting excess current to the ground. Segmented MOVs ensure higher energy absorption capacity, allowing the surge protector to withstand multiple surge events over time
Modes of Protection - Surge protection is provided for key electrical system pairs: L-N (Line to Neutral), L-G (Line to Ground), and N-G (Neutral to Ground)
Easy Installation and Effectiveness - Surge protective devices (SPDs) are economical and easy to install next to any brand of load center, providing whole-home surge protection. They offer the best protection against both externally and internally generated surges when installed as close to the home's electrical panel as possible
3-Stage Protection - This device features a clear, audible alert system that activates when the protection status changes. The protection status LEDs extinguish, an audible alarm sounds, and a red service light flashes, indicating that the device is no longer providing protection

FSPD140 Level 2 Whole House Surge Protector, Rated 140,000 Amps, 120/240V AC Surge Protection Device

【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.
【100% Satisfaction Guarantee】We are committed to providing excellent products and best service for our customers. If you are not satisfied with the product, you can simply return it.
