Product Description

RPM320-40/PCB3 is mainly used for the front end of on-board PCB AC power supply to protect against lightning or other transient overvoltage surge. The product has built-in overheating and overcurrent protection function.It can be used for low-voltage distribution system and electrical equipment to provide class C (type II Classification Test) lightning protection, and can be used for remote monitoring through remote alarm port (dry contact)

Features:
     With built-in overheat and overcurrent protection function, this product can provide low voltage distribution system with Class C (Type II) protection.

1. Optional startup voltage and stable protection circuit.
2. Large discharge current and low let-through voltage.
3. With temperature control open circuit and overcurrent protection functions, safe and reliable; When the product fails, it can be automatically disconnected from the power grid       to completely avoid the fire caused by product failure.
4. It has failure alarm function, and the alarm electrode is closed when the product function is normal; Open circuit in case of product damage.
5. The product is small in size, used for PCB welding and installation, saving space and convenient installation.
