Protective untriggered gaps
Ð-125, Ð-134, P-135, P-136, P-137, P-138
Protective untriggered gaps Ð-125, Ð-134, Ð-135, Ð-136, Ð-137, Ð-138 are designed to protect the equipment of quasi-electronic and electronic systems of communication and other means of wire communication from external electrical action (thunderstorms, the interference induction of high-tension lines and the line-to-line with industrial network).
The version of protective untriggered gaps Ð-125-1, Ð-134-1, P-135-1, P-136-1, P-137-1, P-138-1 with flexible leads on demand.
