Application
Applicable to MCB model JVM16-63, used to control remote signaling device
Combination Scheme
F3 Auxiliary Contact
Contact capacity:
AC: Un=415V In=3A
Un=240V In=6A
DC: Un=125V In=1A
Un=48V In=2A
Un=24V In=6A
Dielectric strength: 2kV/1min
Electro-mechanical endurance: ≥5000
Mounted on the left side of the MCB JVM16-63, indicating “ON”, “OFF” status
of combined MCB.
Terminal Connection Height: H1=31mm H2=16mm H3=1.3mm
S3 Shunt Tripper
Rated insulating voltage(Ui): 500V
Rated power voltage (Us): AC 400, 230, 125V
Operate voltage range: 70~100% Us
Contact capacity:
AC: 3A/400V
AC: 6A/230V
AC: 9A/125V
Dielectric strength: 2kV/1min
Electro-mechanical endurance: ≥4000
Mounting on the right side of MCB/RCBO, used to trip the combined MCB/RCBO by
remote controlling device.
Terminal Connection Height: 19mm
Combination Scheme
SD3 Alarm Switch
Rated insulating voltage (Ui):500V
Rated power voltage (Us): AC 400,230,125V
Operate voltage range :70~100% Us
Contact capacity:
AC:3A/400V
AC:6A/230V
AC:9A/125V
Dielectric strength:2000V/1min
Electro-mechanical endurance:≥4000
Is used to connect ON/OFF auxiliary contact, work as circuit breaker ON/OFF
indicator in case of faulty (tripping)
U3+O3 Over-Voltage/Under-Voltage Tripper
Rated voltage (Ue): AC 230V
Rated insulating voltage (Ui):500V
Over-voltage tripping range:280V ±5%
Under-voltage tripping range:170V ±5%
Electro-mechanical endurance:≥4000
Mounted on the right side of circuit breaker, actuate the combined device to trip in
case of under-voltage or over-voltage,effectively prevent the device from closing
operation under abnormal power voltage condition.
