Auxiliary Alarm

1. Rated insulating voltage (Ui): 500V 2. Rated power voltage (Us): AC 400, 230, 125V3. Operate voltage range: 70~100% Us4. Contact capacity: 3A/400V AC, 6A/230V AC, 9A/125V AC5. Dielectric strength: 2000V/1min6. Electro-mechanical endurance: ≥ 40007. Combined with MCB FDM16-63, and used to control remote signaling device, this Auxiliary Alarm works as circuit breaker ON/OFF indication in case of faulty(tripping)

Over/Under Voltage Protector

1. 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.
2. Rated voltage (Ue): AC 230V
3. Rated insulating voltage (Ui): 500V4. Over-voltage tripping range: 280V ± 5%5. Under-voltage tripping range: 170V ± 5%6. Electro-mechanical endurance: ≥ 4000

Shunt Release

1. Mounted on the right side of circuit breaker, this shunt release is used for tele-control release. It works to tele-control and disconnect electric circuit, connect with fire control alarm system. Tele-control release by emergency button. 2. Rated voltage (Ue): 380V/220V/127VAC; 48V/ 36V/ 24V DC
