EARTH LEAKAGE CURRENT
DETECTOR
SOP-8
DESCRIPTION
The UTC M54123L is a semiconductor integrated circuit with
amplifier for a high-speed earth leakage circuit breaker.
For the amplifying parts of earth leakage circuit breaker, the
UTC M54123L consists of differential amplifier, latch circuit and
voltage regulator.
DIP-8
SIP-8
In normal operating, the UTC M54123L should be connected
to the secondary side of the ZCT (zero current transformers). Here
the ZCT detects leakage current different amplifiers’ both input.
Then the signals which have been amplified are integrated by
an external capacitor. The integrated signal connects to the input
terminal of latch circuit whose output is suitable for the
characteristics of high- speed earth leakage circuit breaker.
Until the input voltage reaches the fixed level, latch circuit
doesn’t become high. Then drives a thyristor which is connected to
latch circuit’s output terminal.

ELECTRICAL CHARACTERISTICS (Cont.)
Notes: 1. Typical values are at Ta=25°C
2. When standard value of voltage (60Hz) between VR and VI is minimum, and output OS is low-level, or
when standard value of voltage (60Hz) between VR and VI is maximum, and output OS is high-level, it is
considered as a good one.
3. When standard value of voltage VSC(ON) is minimum, and output OS is low-level, or when standard value of
voltage VSC(ON) is maximum, and output OS is high-level, it is considered as a good one.
4. Supply current 2 is necessary to keep high in output OS.
5. After applying 30mV between VR and VI and shorting between them, it is considered as a good one if
standard value of IGT flows out of output OS.
6. After supply voltage applies 12V and output OS is high-level, it is considered as a good one in the
standard value of supply voltage and in the low-level of output OS.
7. Operating time is a time from applying fixed input till operating latch circuit in 0.047μF between OD and
GND.

Note: Gate current must be selected.
Please select voltage resistance by AC supply voltage
Note: The value of R1, R2, C4, and C5 should be chosen in order to keep at least 12V in Vs.
Please connect C4 (>1μF) and C2 (<1μF).
ZCT and load resistance RL of ZCT are connected between input pin 1 and 2.
Protective resistance (RP=100Ω) must be insurted.
RL and amplifier’s output (in Pin 4) regulates sensitivity current
External capacitor C1 between pin 4 and GND is used for noise removal.
Please connect a varistor or a diode (2 pcs.) to ZCT in parallel, because of when large current is grounded in the
primary side (AC line) of ZCT, the following situation can be abandoned: The wave form in the secondary side of
ZCT is distorted and some signals do not appear in the output of amplifier.
Please connect capacitor (about 0.047μF) between pin 6 and pin 7.
Capacitor C6 between pin 1 and GND is about 0.047μF for removing noise.
