Penta MTAG0310FCUA, LED Voltage Indicator, 10000V ac / 2217791

The Sibille voltage detector is designed for proving dead, making sure that nominal voltage is actually absent on a circuit in an HV distribution system between 3 to 10 kV. This device will detect any nominal voltage on over head lines and stations. It will avoid detecting most induced voltages in order to allow grounding operations. It prevents accidental interchange of housing or circuitry when the battery is replaced.Optimised indication 100 dB sound signal It is compliance with European directives
