Field of use:

The separation spark plug is used in the electrified railway network, with the nominal voltage at the contact line of 25 KV, having the role of ensuring the protection of the centralization installations in case of accidental overvoltages. It is connected between the railway rail and the metal connection of the object to be protected.

Technical-constructive parameters:

• Initial voltage limit: lower 500 V; upper 800 V;
• Non-priming voltage value: 200 V;
• Nominal passage capacity: 1000 A;
• Overall dimensions: F 62 x 260 mm;
• Mass: approx. 1.1 Kg.
