Frequently Asked Questions
What is the primary function of this 150VDC Surge Protective Device?
It is designed to protect DC electrical systems, such as solar photovoltaic installations and industrial control systems, from voltage surges caused by indirect lightning or switching events.
What does the Type 2 (T2) classification mean?
T2 indicates that the device is a secondary surge protector, tested with an 8/20μs current waveform, suitable for installation in sub-distribution boards to protect sensitive electronics.
How do I know if the device needs to be replaced?
The device features a built-in visual status indicator. When the indicator changes color (typically from green to red), it signifies that the protective component has reached its end of life and the module should be replaced.
Is this device easy to install in existing cabinets?
Yes, it is designed for standard 35mm DIN rail mounting, making it compatible with most industrial and residential electrical enclosures.
What is the benefit of the three-pole (3P) design?
The 3P design allows for comprehensive protection of the positive (+) line, negative (-) line, and the ground (PE), ensuring no path is left vulnerable to surges.
Can it operate in extreme weather conditions?
The device is engineered to operate reliably in temperatures ranging from -45°C to +85°C, making it suitable for various climates and industrial environments.
