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 delivers a substantial 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
