Home Surge Defender 240VAC HSD240V


  • Protects 120V and 240V panel circuits
  • 260kA surge rating
  • Provides industry leading protection to L1-G, L2-G, L1-L2, L-G, L-N circuits
  • Protects connected devices from damage due to Lightning, Solar Flare, EMP (All phases), Grid Voltage Surges, and more
  • Surge Protector must be installed in series with a circuit breaker or fuse of at least 20A to short circuit protection (NEC requires a 20A double pole circuit breaker to be used)
SKU: HSD240V Category:

The Home Surge Defender is designed for both residential and commercial applications. Class leading protection for sensitive electronic equipment, from the stress and damage due to transient voltage spikes. The products work by diverting the overvoltage surges away from the the protected devices and shunting them to ground in fractions of a second (Much faster than a typical current controlled protection device). Protects the electrical circuit by providing up to 260kA of surge current capacity. Protects connected devices from damage due to Lightning, Solar Flare, EMP (All phases), Grid Voltage Surges, and more.
