FAQ (Frequently Asked Questions)

Q1: What is the lifespan of the ABB 07KR240 SPD?
A1: The lifespan depends on exposure to surges, but under normal conditions, it can last 5-10 years.

Q2: Can this SPD be used in outdoor installations?
A2: No, it is rated for indoor use (IP20). For outdoor applications, an additional enclosure is required.

Q3: How do I know if the SPD has failed?
A3: The status indicator will show a red or off state when the device is no longer functional.

Q4: Is the ABB 07KR240 suitable for DC systems?
A4: No, this model is designed for AC systems only. For DC, consider the OVR PV series.

Q5: What is the replacement procedure for a failed SPD?
A5: Disconnect power, remove the old unit, and install a new one following the same wiring configuration.

Q6: Can multiple SPDs be connected in parallel?
A6: Yes, for enhanced protection, but they should be coordinated (e.g., T1 + T2 configuration).
