Application
The 3UG30 81 monitoring relay is suitable for insulation
monitoring of AC systems with one or three phases in
ungrounded networks (IT networks).
Supply voltage
The 3UG30 81-1AK20 has alternative voltage terminals. Only
one supply voltage is permitted to be connected to it! Terminals
A1 and A2 are used to connect 230 V AC and terminals A1 and
B2 are used to connect 115 V AC.
The 3UG30 81-1AW30 has a wide-range input of 24 V to
240 V AC/DC on terminals A1 and A2.
