SN2 Series Voltage Presence Indicators

The SN series indicators meet the requirements of the LRM system and the IEC/PN-EN 61243-5 standard.

• SN2: A self-powered indicator version.
• SN3: Includes binary outputs for field interlocks and requires 24V DC power.

These indicators come with a single capacitance matched to the capacitive insulator and the switchgear’s rated operating voltage. Use the calculator below to select the correct capacitance.
