The First Defense 350 Series 50 amp Plug-in Marine Surge Protector offers your 120/240 volt marine electrical surge protection in a portable design. This 50 amp marine surge protector offers All Mode Protection – it protects Line 1 to Line 2; Line 1 to Neutral, Line 2 to Neutral, Line 1 to Ground, Line 2 to Ground, and Neutral to Ground.
The 350 Series 50 amp surge protector protects against ring wave transients, those extremely fast, low energy surges that cause cumulative damage to your electronics and computerized equipment with standard EMI/RFI Filtering. This is often referred to as sine wave tracking. For the ultimate in transient protection, consider ordering the optional Surge Eraser Technology™ which provides enhanced sine wave tracking protection.
We realize that ordering the right 50 amp surge protector can be a little confusing. Every marine surge protector claims to be able to protect your electronics. You’re concerned about let-through voltage – the amount of excess voltage that continues to move through your electrical system after the surge protector has activated. Our units have the lowest let-through voltages in the industry. This means less damaging surge voltage is allowed to pass through the surge protector and into your electronics. That’s why you can find SSI surge protectors on the US Navy fleet, protecting the vital electronics that keep our country safe.
The First Defense 50 amp Marine Surge Protector offers 120 kA peak surge current per phase. Unlike other surge protectors that offer much lower protection levels, we understand the need to protect your boat from the poor power quality found in every marinas.
Other features include NEMA 4X water tight enclosures. Unlike other companies that use water resistant electrical boxes, the NEMA 4X water tight enclosure is the ultimate in weather resistant protection.
To protect against moisture and vibration, the First Defense 350 Series Marine Surge Protector features circuitry encapsulation. Another way we go the extra mile to provide you with the very best marine surge protection possible.
Because we are constantly seeking to improve our products, specifications are subject to change at any time.
