The TRS-C40 is a high-capacity Type 2 surge protective device designed to safeguard AC distribution networks exposed to stronger overvoltage stresses.
With 20 kA nominal and 40 kA maximum discharge capability, it provides robust MOV-based surge mitigation for medium-risk industrial and commercial electrical systems.
Designed for 230/275 V AC environments, the TRS-C40 offers a balanced combination of fast protection, stable clamping voltage, and long-term service reliability.
The modular pluggable design simplifies maintenance procedures, while the visual red fault indicator ensures clear monitoring without additional tools.
This model is ideal for installations requiring enhanced surge endurance, such as facilities with long cable runs or areas prone to induced lightning surges.
Applications
Industrial power networks with increased surge exposure
AC distribution boards in commercial facilities
Protection of machinery, HVAC equipment, and automation systems
Mid-level surge protection for main or sub-panels
Installations following Type 2 SPD requirements per EN 61643 standards
