Relays of the OMSh and ASh Types

Neutral electromagnetic relays OMSh, ASh

Electromagnetic neutral relays of the OMSh, ASh types

Electromagnetic neutral relays of the OMSh and ASh types are designed to establish electrical dependencies that prevent the occurrence of unacceptable safety conditions for the operation of signaling, centralization, and blocking (SCB) devices in railway and metro transportation.

Electromagnetic neutral relays are manufactured in the following types: OMSh2-46, OMShM-1, ASh2-180/0.45, ASh2-1.

All types of relays operate in a gravitational release mode based on the armature’s operation.

The mass of the relay does not exceed 2.2 kg.

The dimensional specifications of the relay are: 114 x 89 x 210 mm.
