LNMA2-OF/LNMA2-OFB Auxiliary Contact

·LNMA2-OF Contact capacity

AC: Un=415V In=6A; Un=125V In=1A

·Dielectric strength: 2kV/1min

·Electro-mechanical endurance: ≥5000

·Mounted on the left side of the

·DPN LNMN2-40, MCB LNM3-125, B Type RCCB

·LNL1-63, etc., indicating “ON” “OFF” status of

·Combined MCB/RCCB.


LNMA2-SDAlarm Switch

·Rated insulating voltage(Ui): 500V

·Rated power voltage(Us): AC 400, 230, 125V

·Operate voltage range: 70~100% Us

·Contact capacity AC: 6A/415V; AC: 1A/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).


LNMA2-S2/LNMA2-S2+OF Shunt Tripper

·Rated insulating voltage(Ui): 500V

·Rated power voltage(Us): AC 400, 230, 125V

·Operate voltage range: 70~110% 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

Used to trip the combined MCB by

Remote controlling device.


LNMA2-U2+O2 Over-voltage/Under-Voltage Tripper

·Rated voltage (Ue): AC 230V

·Rated insulating voltage (Ui): 500V

·Over-voltage tripping range: 270V±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.
