Frequently Asked Questions
What is the primary function of this Type 2 Surge Protective Device?
It is designed to protect electrical installations and sensitive equipment against indirect lightning strikes and transient overvoltages by limiting the voltage and discharging surge currents.
How does the visual status indicator work?
The visual indicator provides a real-time health check. Typically, a green window indicates the device is operational, while a change in color (often to red) signals that the protective module has reached its end of life and requires replacement.
Can this SPD be used in renewable energy systems?
Yes, it is suitable for renewable energy systems, as well as industrial power distribution, commercial buildings, and manufacturing control panels.
What are the installation mounting requirements?
This device is designed for standard DIN rail mounting, allowing for easy integration into most modern power distribution boards and control cabinets.
Is the housing material safe for industrial use?
Absolutely. The housing is made from flame-retardant thermoplastic, ensuring high safety standards and durability in various industrial environments.
What is the significance of the 20kA and 40kA ratings?
20kA represents the Nominal Discharge Current (In) the device can handle multiple times, while 40kA is the Maximum Discharge Current (Imax) it can withstand in a single event.
