EMP Shield Generator Protection 120/240V Lightning CME Surge MIL-STD IP66

EMP Shield Generator Protection – 120/240V Lightning, CME, and Surge Defense

Protect your generator and backup power system with the EMP Shield Generator Protection Module (SP-120-240-G). Designed for 120V–240V single-phase generators, this unit helps safeguard sensitive electronics and electrical components from lightning strikes, coronal mass ejection (CME) events, electrical surges, and electromagnetic disturbances.

Using advanced surge suppression technology, the EMP Shield detects and safely diverts excess voltage before it can damage connected equipment. The device reacts in less than one billionth of a second to help prevent destructive voltage buildup. 

This protection system is designed specifically for generators and backup power systems to help ensure your equipment remains functional when you need it most.

CME and Lightning Protection

• CME surge protection rated up to 228,000 amps 
• Lightning protection backed by EMP Shield’s $25,000 connected equipment warranty policy
• Protection against E1, E2, and E3 electromagnetic pulse phases
• Ultra-fast response time to transient voltage events

Military and Government-Tested Standards

EMP Shield generator protection devices are designed and tested to meet or exceed major military electromagnetic resilience standards, including:
