Overview
SIRIUS 3UL23 residual-current transformer
The 3UL23 residual-current transformers detect residual
currents in machines and plants. They are suitable for pure
AC residual currents or AC residual currents with a pulsating
DC fault current component (transformer type A in accordance
with DIN VDE 0100-530/IEC TR 60755).
Together with the 3UG4625, 3UG4825 residual-current monitor-
ing relays for IO-Link or the SIMOCODE 3UF motor management
and control device they enable residual-current and ground-fault
monitoring.
The 3UL2302-1A and 3UL2303-1A residual-current transformers
with a feed-through opening from 35 to 55 mm can be mounted
in conjunction with the 3UL2900 accessories on a TH 35 stan-
dard mounting rail according to IEC 60715.
