Made in Japan
Manufacturer: Hasegawa Electric
Model : EFS-1 (Circuit Guard)

Features:

• Prevents short circuits in track circuits due to misrecognition and other errors during grounding work on direct current electric lines (DC1500V).
• Equips grounding wires with a diode function to prevent track circuit current and hence prevent short circuits.
• However, it allows earth leakage current when the overhead lines are charged.

※Open price. Note: Does not include a grounding hook.
