CMP relay - Current monitoring AC input

Description

Current monitoring railway relay with two change-over contacts. Suitable for AC currents (16-60 Hz) and no auxiliary power supply necessary. The pull-in current is adjustable with a lockable knob. The contacts are weld-no-transfer contacts: they are mechanically forced in the same position.

The construction of the relay and choice of materials makes the CMP relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to very humid environments.

No external socket necessary, the relay can be mounted directly on a 35 mm rail without extra fasteners, or on any surface via 2 screws.

Application

These relay series are designed for rolling stock applications. The CMP is used in applications for accurate current monitoring.
