Mersen Electrical Power provides a comprehensive line of electrical protection products including current-limiting fuses (low voltage, general purpose, medium voltage, semiconductor, miniature and glass, and special purpose) surge protective devices, elevator switches, and our fused coordination panelboard.


Mersen’s comprehensive power fuse offering covers a complete range of applications and a complete range of circuit-protection needs. Whether it’s the high current-limiting capacity of our Amp-Trap® 2000 power fuses, the characteristics of our Tri-Onic® Time-delay fuses, or another application-specific power fuse solution, Mersen has the fuse you need.


Mersen offers a comprehensive suite of Surge Protection products, covering every voltage need within a facility. An industry innovator, Mersen developed the first surge protection device to pass UL 1449 3rd edition (now 4th edition) safety requirements. All Mersen SPDs feature our patented Thermally Protected MOV (TPMOV®) technology, a fail-safe surge protection solution without the need for additional upstream protection. As a result, the Surge-Trap® product line offers the lowest installed cost surge protection products on the market.

Mersen offers surge protection products ranging from point-of-use protection to complete facility protection. The Surge-Trap product line represents the broadest suite of products for all your application requirements.

Thermal MOV protection (TPMOV). Thermal protection eliminates an MOV’s hazardous and destructive failure modes

Overvoltage is solely managed by TPMOV technology. This technology eliminates the need for additional wiring, fuse components, and costly installation time

Non-Fused MOV protection. TPMOV is the only non-fused MOV on the market

Industry Innovation. Mersen developed the first SPD product to pass UL1449 3rd edition (now 4th edition) safety testing utilizing our patented TPMOV technology

Highest Short Circuit Current Rating (SCCR). Surge-Trap products feature the highest SCCR rating available for any surge protection device, allowing for higher safety ratings and protection

Isolated MOV. Surge-Trap products provide fail safe protection by isolating the MOV at the end of life

Elevator Switches

Mersen’s Fusible Shunt Trip Switch is a UL Listed industrial control panel offering remote load-break disconnection capability to emergency circuits. It meets many different code requirements with the protection and safety in elevator shafts. Panels built for elevator applications feature control transformers (fusing both primary and secondary sides), a fire safety interface relay with a fire alarm voltage monitoring relay, and mechanically interlocked auxiliary contacts. An array of available options allows for maximum functionality to be built into a single compact panel.

Fused Coordination Panelboard

Mersen’s Fused Coordination Panelboard is designed to meet requirements defined by the National Electrical Code (NEC)® to protect critical power operations. These panels are provided with a default short circuit current rating (SCCR) of 200kA and provide overcurrent protection through a combination of a circuit breaker and a fuse. The circuit breaker is designed to operate on overloads up to 2 times their rating and the fuse over 2 times up to 200kA. Mersen’s Fused Coordination Panelboard can simplify the process in achieving code compliance for designers.
