The TR30B+C is a robust Type 1+2 surge protective device designed to deliver reliable protection against both direct lightning currents and transient surges in low-voltage AC distribution networks.
With its compact footprint and 2-pole/4-pole availability, it integrates smoothly into main distribution boards and sub-distribution panels across residential, commercial, and industrial facilities.
Featuring a hybrid MOV architecture optimized for durability, the TR30B+C provides 4.5 kA (10/350 μs) lightning impulse capability and a high 60 kA (8/20 μs) maximum discharge capacity. Its ≤1.5 kV protection level offers consistent limitation of overvoltages, ensuring that connected equipment continues to operate safely even during severe electrical disturbances.
A red fault indication window provides instant visual status feedback, while optional potential-free remote signaling contacts enable integration with monitoring, alarm, or automation systems to support real-time supervision.
The pluggable module design helps reduce maintenance time, allowing quick replacement without disturbing existing wiring.
Engineered for 35 mm DIN-rail mounting, the TR30B+C is well suited for installations requiring higher discharge capacity, dependable surge suppression performance, and efficient device servicing.
Applications
Main or sub-distribution boards requiring higher energy handling in Type 1+2 protection
Residential, commercial, and industrial AC power systems operating at 230V AC
Facilities with or without external lightning protection systems
Power networks exposed to frequent switching operations or moderate lightning conditions
Installations requiring remote status signaling for centralized monitoring
Panels prioritizing tool-free module replacement and easy maintenance
