BD-U200 relay - Latching, plug-in 4 pole

Summary

Description

Plug-in bistable railway relay with three change-over contacts and one normally closed contact. The contacts remain in the last powered position. Bistable by means of a permanent magnet.

Standard equipped with magnetic arc blow-out for high breaking capacity and long contact life. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions.

The construction of the relay and choice of materials make the BD-U200 relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to humid environments.

Compact design, choice of many options and a wide range of sockets makes the BD-U200 relay an easy and flexible solution to use.
