Light signalling breakers

Breakers are used in signalling systems to provide an intermittent light signal in signalling systems and are designed for use in DC circuits.
Interrupters are produced of the following types:
ORS - DC relay interrupter;
ORS2 - double DC relay interrupter

The breakers have protection class IP46. Cable entry is via glands. The devices have grounding bolts. The breakers of ORS type are manufactured for voltage 24, 110 and 220 V DC.

Structure of the complete breaker code
After the type of interrupters the variant by DC supply voltage is indicated:
A0 - 24 V
A1 - 110 V
A2 - 220 V.

Climatic version OM4, cable connection through glands. The devices have two switching contacts at the output, which provides connection of up to four signalling circuits simultaneously. Since the contacts are self-contained, the signalling supply voltages can be any
