Frequently Asked Questions

Q: What is the difference between the 40A and 63A versions of the SVP726 protector?

A: The two variants differ in maximum rated current capacity. The 40A version is suited for smaller residential or light-commercial circuits, while the 63A version handles heavier loads in larger commercial or industrial installations. Both offer the same voltage protection range and feature set.

Q: Will the SVP726 automatically restore power after a voltage fault?

A: Yes. The SVP726 is a self-resetting protector. Once the voltage returns within the configured safe range and the user-set delay period (1–300 seconds) elapses, the unit automatically reconnects power without any manual intervention.

Q: Can I adjust the voltage trip points after installation?

A: Absolutely. The overvoltage threshold (240V–300V) and undervoltage threshold (140V–210V) are both fully adjustable via the front-panel SET key at any time, even after the unit is installed on the DIN rail.

Q: Is the SVP726 compatible with standard DIN rail panels?

A: Yes. The SVP726 uses a standard buckle guide-rail (DIN rail) installation method, making it compatible with most residential and commercial distribution boards and panel enclosures.
