Frequently Asked Questions
Can Heschen protectors be used directly in European countries?
Yes. Most models (e.g., LYD1-C40/385, HS-40D) have CE and VDE certifications, meet EU electrical standards, and can be used directly.
What does it mean when the SPD indicator turns red?
A red light means the SPD is faulty or has been damaged by surges. Replace it immediately to avoid losing protection.
Is the 385V SPD suitable for North America's 120/240V power grid?
No. The 385V model is for 380V three-phase systems. For North America, choose 275V single-phase models (e.g., HS-40D).
Do I need to install a fuse before the SPD?
Yes. It's recommended to install a 63A fuse or circuit breaker to prevent short circuits and protect the SPD.
Can PV DC SPDs (e.g., LYD1-PV1000) be used for AC circuits?
No. DC SPDs are designed specifically for DC circuits. Using them for AC will damage the device and fail to provide protection.
