Product Introduction
The OMRDON dual power surge protection device box is suitable for lightning protection of TN-S, TN-C-S, TT, IT and other power supply systems with AC 50Hz/60Hz, 380V and below. Its design complies with GB18802.11 and IEC61643-11 technical standards, and can simultaneously provide surge protection for two three-phase power supplies. It has local and remote monitoring and alarm functions, suppresses electromagnetic induced overvoltage and overcurrent caused by induced lightning or operation overvoltage in the power supply network and information system, and ensures the protection of the insured
The protective equipment is always in a safe and protected state.
Features:
1. It can withstand up to 65KA (8/20 μ s) lightning current surge, with an action response time of less than 25ns.
2. Real time monitoring and alarm of main and backup lightning protection switches/power supply status.
3. Real time monitoring and alarm of the status of main and backup lightning arresters.
4. The monitoring of lightning strikes can record the number of lightning strikes (up to 99, can be reset to zero) and query historical records.
9. The built-in surge protector has a visual alarm window color indicating the working status of the protection, green (normal) and red (fault).
10. This product can be built into the power distribution box.
Product installation precautions:
1. During installation, the power must be disconnected and live operation is strictly prohibited.
2. The connecting wires must use multi stranded copper core wires, and the cross-sectional area of the wires must meet the requirements of engineering installation. During installation, pay attention to connecting the live wire of the incoming line to the L terminal of the lightning protection box circuit breaker, and connect the PE ground wire to the PE grounding copper bar of the lightning protection box. Do not reverse or miss the connection.
3. When the green indicator light is on, it indicates that the power supply is working properly; When the yellow light is on, it indicates that the lightning arrester is working properly; When the red light is on, it indicates that the lightning arrester has failed and needs to be replaced or repaired in a timely manner.
4. When the remote alarm sounds an alarm, it indicates that the lightning protection box has failed or there is a problem with the circuit (with a buzzer sound alarm), and it must be repaired or replaced in a timely manner.
5. When the lightning strike counter has a digital display (1-99), it indicates that lightning current is passing through; The reset button on the lightning protection box cover panel can be used to reset to zero, and the counter will be counted again
