MCG Surge Protection
Surge Protection is Our Only Business
50+ Years of Perfect Protection
An ISO 9001:2015 Company
MCG Surge Protection, Inc. was nominated by
Northrop Grumman (formerly TRW Systems) for
"Small Business Vendor of the Year."
MCG is intensely dedicated to one area – the design, development, and manufacture of highly reliable surge protection devices. Products you can depend on when it counts.
Lightning and power line surges can seriously damage or disrupt operations in hospitals, financial institutions, military installations, and other mission-critical activities. The 560LS, MCG’s flagship AC Power Line Main Service Panel Protector, through its extraordinary surge current diversion capability, protects your sensitive system from damaging transients, thus eliminating "downtime" and its associated financial and lost labor costs.
AC Power Line Protectors, range from full facility protectors at the main service panel (Ip-400kA) to branch and local panel protectors to compact 15A OEM protectors.
Data Line Protectors employ a three-stage heavy-duty hybrid protection circuit that is unique in the industry. This superior design blends high speed clamping with brute force diversion capability. They are offered in all popular voltages and connectors.
Our goals are simple and straightforward:
- Build high quality, dependable products
- Provide excellent value for the money
- Supply accurate information for customers to make an informed decision
- Avoid puffing and promotion of spurious benefits
- Stand behind our products with an extraordinary "No Nonsense" warranty (Twenty-Year; lifetime on protection modules).
- Before and after sale support from MCG staff. People, not voice mail, solve problems.
If you are already a customer, we appreciate your ongoing support of MCG products. If not, the next time you are in the market for surge protectors, consider giving us the opportunity to show you what a company dedicated solely to surge protection can do for you.
MCG is a woman-owned business
Michael J. Coyle founds MCG Electronics in Bay Shore, NY. A graduate of New York University, School of Engineering (BSEE), his subsequent engineering activities at Sperry Gyroscope and Hazeltine centered on high power (10 megawatt) radar systems and big voltage systems (to270kV) with specific attention to pulse modulators.
