BLT-T2-1S-305-UT - Type 2 surge arrester
Type 2 surge arrester for universal mounting in lights, cable connection boxes, installation boxes, sill-type trunking, underfloor installations or direct installation in the end device. Specifically for insulation class I with optical fault indication. Installation in branch or through wiring. Version: 230 V AC
- Optimal additional protection of the building installation for longer service life and increased availability of the end devices
- Optimal protection of the power supply for longer service life and increased availability of the LED lighting
- Excellent level of information provided, thanks to shutdown function for the load circuit in the event of an error
- Simple condition monitoring without voltage on the device with a mechanical/visual status indicator
- Flexible installation, thanks to mounting via integrated elongated holes
- Stub or through-wiring connection
- Flexible installation
- Fixed via integrated elongated holes
- Compact design
- Optical, mechanical status indicator
- Compact design
- Universal use for street, tunnel or object lighting
- L' signalizes the failure of the surge protective device due to disconnection of the power supply to the lights
