The TRS4-C40 is a robust Type 2 surge arrester engineered for installations needing high-capacity transient protection.
Delivering 20 kA nominal and 40 kA maximum discharge capability, it is suitable for commercial and industrial sites subject to elevated surge energy, long cable runs, or frequent switching operations.

Its pluggable module structure enables efficient on-site replacement, reducing system downtime. The bright red fault window provides clear visual alert when replacement is necessary.
With a low protection level and rapid response time, the TRS4-C40 helps safeguard sensitive loads such as automation controllers, industrial machinery, and electronic equipment.

Applications

Industrial AC distribution networks
Commercial buildings with extensive cabling or outdoor feeders
Protection of mission-critical or sensitive electrical loads
Facilities with frequent switching transients or unstable grid co
