Optical remote indicator for ground fault and short circuit messages

The external flashing lamps types BL4.1 and BL4.2 are used for clearly visible indication of ground faults and short circuits in outdoor areas. They are housed in a robust polycarbonate enclosure with IP65 protection and feature an LED with a 35° beam angle for targeted signaling. Depending on the model, power is supplied either directly via the connected display device or via an integrated lithium battery. This allows the flashing lamps to be flexibly integrated into existing fault display systems.

  • Visible error display for outdoor applications
  • Robust IP65 polycarbonate housing
  • Type BL4.1: Power supply directly via display device (maintenance-free)
  • Type BL4.2: Battery power supply (3.6 V lithium, 1/2 AA)
  • Automatic detection of continuous or momentary contact
  • Adjustable flashing duration for momentary contact (default 2 hours)

For targeted fault localization in medium-voltage networks, we also offer solutions in the area of short-circuit indicators, ground fault indicators and combined ground fault and short-circuit indicators .
