Our solution: You need fail-safe surge suppression, and the
reliability and cost savings of Mersen’s Surge-Trap® Surge
Protective Devices with patented TPMOV® Technology inside.
Surge-Trap SPDs provide a compact, space saving solution.
Plus, unlike other SPDs on the market, they do not require
additional overcurrent protection, thus offering reduced
installation costs.

TPMOV® Technology
Thermally protected MOV (TPMOV) technology
Mersen’s patented TPMOV® technology eliminates common failure
modes that occur in the field with standard metal oxide varistors. Internally the
TPMOV is comprised of a voltage clamping device and a disconnecting apparatus
that monitors the status of the metal oxide disk making the TPMOV a fail-safe
device. In the event of an overvoltage breakdown the metal oxide disk is securely
disconnected from the system power by an arc shield. Upon failure the TPMOV is
also equipped with a visual pin indicator as well as a normally open micro-switch
providing remote indication, if applicable.
The TPMOV is rated for 50kA - 8/20μs peak surge current and is available for
maximum continuous operating voltages (MCOV) from 150V to 550VAC. No
additional fusing or overcurrent protective device is required when using the
TPMOV as compared to most MOV’s on the market today.
The TPMOV footings are similar to that of equivalent voltage ratings of traditional
25 to 40mm MOV’s. The TPMOV can be utilized on existing systems that utilize
traditional MOV’s without costly board redesigns. See dimensional drawings on the
following page.

VSP MOV Protector Fuse
Surge Suppression Fuses
Mersen surge suppression fuses are specially designed to address the protection
of SPD systems. Our surge suppression fuses have been specially designed to
withstand 8x20 µSec surge pulses without opening, allowing the SPD system to
react to the surge. All surge suppression fuses have a 8x20 µSec surge rating, not a
continuous current rating. Under AC short circuit conditions these surge suppression
fuses are very current limiting.
Features/Benefits:
Applications:
•• VSP fuses rated 600VAC, 200kA I.R.
•• Protection of surge protection
•• Surge ratings of 5-100kA 8 x 20
devices (SPD)
•• Coordination with other protection
µSec capacity
•• Various mounting configurations
