The TRS2-D20 is a compact Type 2 surge protective device engineered for AC sub-distribution systems requiring dependable mid-level surge suppression.
Using high-quality MOV technology, it provides 10 kA nominal and 20 kA maximum discharge capability, ensuring stable protection against switching surges and induced lightning overvoltages within 230 V AC networks.

Its pluggable module design allows fast and convenient replacement without service interruption, while the built-in visual red fault indicator offers immediate status recognition.
Designed for standard indoor electrical panels, the TRS2-D20 features a slim 2P/4P configuration to fit compact distribution spaces and supports optional remote signalling for integration into monitoring systems.

With fast response time and a robust operating temperature range, it is a reliable choice for residential, commercial, and light industrial power installations that require consistent Type 2 surge protection.

Applications

Residential and commercial AC distribution panels
Secondary protection for terminal equipment and control devices
Sub-distribution boards where compact Type 2 SPD is required
Installations using automation loads or switching circuits
Systems requiring optional remote signalling for fault monitoring
