Mersen’s 510TPMOVTS TPMOV7 surge suppression component combines industry-leading TPMOV technology with 50% more surge capacity (75kA, 8/20μs) in the same footprint as standard 25–40mm MOVs. Each unit integrates a voltage clamping device and a disconnecting apparatus that monitors the metal oxide disk, making it a fail-safe device. In overvoltage events, the metal oxide disc is securely disconnected by an arc shield. The device includes a visual pin indicator and a normally open micro-switch for remote failure indication. Rated for maximum continuous operating voltages (MCOV) from 150V to 320VAC, the 510TPMOVTS is designed for industrial applications requiring reliable, thermally protected surge protection.

Mersen’s TPMOV7 surge suppression component (SKU: 150TPMOVTS) delivers 50% more surge capacity in the same footprint as standard MOVs, rated for 75kA peak surge current (8/20μs). Designed for maximum continuous operating voltages (MCOV) from 150V to 320VAC, this fail-safe device eliminates common field failure modes of standard metal oxide varistors. Internally, it combines a voltage clamping device with a disconnecting apparatus that monitors the metal oxide disk, ensuring secure disconnection from system power during overvoltage breakdown via an arc shield. The TPMOV7 series includes a visual pin indicator and a normally open micro-switch for remote indication, enhancing system monitoring and safety. With a short-circuit current rating (SCCR) of 200kA and response time under 1 nanosecond, the TPMOV7 is ideal for protecting sensitive industrial equipment, power distribution systems, and renewable energy installations. Its thermoplastic enclosure (UL 94 V-0 rated) and operating temperature range of -40°C to +85°C ensure reliability in harsh environments. Compatible with 25–40mm MOV footprints, the TPMOV7 series provides a consistent, high-performance solution for surge protection without requiring footprint changes.
