Editor's Notes

November 29, 2018:

Added the Leviton 51120 Series for its 3-phase operation and integrated diagnostic capabilities. Also included the Siemens FS140 for the weather-resistant durability of its enclosure and rapid response times. The modular design of the Square D Surgebreaker Plus makes it a good choice for protecting large appliances and HVAC systems. Also added the Intermatic IG1240RC3 for its compact design and thermally-protected components. Finally, added the PEFL Kvar due to its ability to reduce energy consumption and recycle power.
