Application Overview:
The RDF series surge protector is suitable for low-voltage AC power distribution system. The AC power supply is connected in parallel with the requirement. It protects the equipment from the external environment (such as lightning and electromagnetic interference) or the system (such as the switching effect of the system, the start of inductive and capacitive loads, or shutdown) caused by the impact of surge and transient overvoltage.
RDF30-1260-3+1 is mainly composed of three MOV power modules and one GDT module. It provides L-PE protection and can remotely monitor its operating status.
Key Features:
- Large discharge current capacity and low residual voltage
- Equipped with common mold/differential mold and reliable thermal trip protection device
- With fault indication and optional centralized remote signal alarm dry contact
- Fast response time, action within 20 nanoseconds
- Module design, easy to install and replace
