Mersen Surge-Trap® Surge Protective Devices

Mersen, an industry pioneer in surge protection technology, has developed a world-class suite of surge protective devices for any and all applications, from facility service entrance to individual equipment point-of-use. Mersen's SPDs provide advanced overvoltage protection by featuring TPMOV® Technology to meet today's toughest requirements.
Most surge spikes originate from within a customer’s own facility. In fact, nearly 80% of all surge problems are directly attributed to power disturbances from equipment within the facility. Any facility with motors stopping and starting, light load panels being turned on and off frequently, and other potential power disturbances is at risk for damage caused by a surge spike.
Of course, surges in electrical power can also originate outside of a facility, accounting for roughly 20% of facility transient problems. These surges may be caused by utility grid switching, lightning strikes, switching of capacitor banks, and electrical accidents.
Although many transients are not predictable, damage to a facility is preventable with a proven and tested surge protective device.
Surge-Trap® NEMA Type 1 wallmount and panelmount devices feature surge capacities ranging from 50 to 450kA designed with Mersen’s industry leading TPMOV® technology inside, making these the safest and most reliable products on the market. Options include surge counter, through the door disconnect switch, audible alarm, dry contact, and EMI/RFI filtering. As a Type 1 SPD, Mersen’s Surge-Trap NEMA SPDs are suitable for any and all applications from facility service entrance to individual equipment point-of-use.
Surge-Trap® DIN-Rail surge protective devices provide advanced overvoltage protection for OEMs and panel builders looking for devices within existing control panels and panelboards. They utilize Mersen's patented TPMOV® design, which does not require fuses, a fuse holder, or additional wiring to meet UL 1449 Fourth Edition standards, thus providing substantial cost savings and reduced installation times.
