CE certification ISO certification RoHS certification

The TRS7-B80 is a robust Type 2 AC surge protective device designed for 380V low-voltage distribution networks. Built for use in sub-distribution panels, it provides a strong defensive layer against switching surges and indirect lightning effects, ensuring stable protection for downstream electrical equipment.

Using a high-performance MOV protection module, the TRS7-B80 delivers consistent surge suppression suitable for environments with frequent electrical disturbances.
Its pluggable-module design allows fast replacement during maintenance, minimizing downtime and simplifying service work in both new installations and retrofit projects.

The device incorporates a clear red visual status indicator for immediate fault identification, while optional potential-free remote signaling enables integration with monitoring or building-management systems.
Its compact form factor, IP20 enclosure, and DIN-rail mounting make it easy to deploy inside standard distribution cabinets.

Engineered for long-term stability, the TRS7-B80 maintains reliable operation across wide temperature and humidity ranges, making it suitable for residential buildings, commercial facilities, and light-industrial power networks.

Applications

Sub-distribution boards in residential, commercial, and industrial buildings
Secondary surge protection in multi-stage SPD systems
Electrical networks with motors, pumps, HVAC units, or switching-heavy loads
Lighting and general-purpose branch circuits
Installations requiring visual fault indication and optional remote monitoring
Systems where quick module replacement improves maintenance efficiency
