The TRS-D20 is a durable Type 2 surge protector built for general-purpose AC power systems requiring improved surge handling.
Rated for 10 kA nominal and 20 kA maximum discharge current, it offers reliable MOV-based protection against switching surges and induced lightning overvoltages.
Its low protection level ensures stable performance with sensitive electrical equipment, while the fast <25 ns response time minimizes transient impact.
The pluggable cartridge design enables effortless module replacement without rewiring, and the built-in red status window provides immediate fault detection.
Engineered for 230 V / 275 V AC applications, the TRS-D20 is suitable for a wide range of industrial and commercial environments where consistent surge mitigation is essential.
Applications
Commercial and industrial power distribution panels
Protection of equipment exposed to moderate surge risk
AC distribution boards requiring 20 kA Type 2 SPD
Systems integrated with switching loads or automation devices
Installations requiring tool-free module replacement
