RC-19A relay - Current monitoring

Name: RC-19A relay - Current monitoring
Brand: Own brand
Availability: InStock

This relay is obsolete from January 1, 2023

Summary

Description

Current monitoring railway relay with one change-over contact. Suitable for AC currents. The input consists of a ring core saturation transformer: place the wire with current to monitor simply through the transformer. Ease of installation and high continuous overcurrent possible. Protection against short circuit and low impedance. The relay is also suitable for earthfault protection.

Adjusting the pull-in current for lower values by multiple threading through the transformer.

The construction of the relay and choice of materials makes the RC-19A relay suitable to withstand low and high temperatures, shock & vibrating and dry to very humid environments.

No external socket necessary, the relay can be mounted on any surface via 2 screws.

Application

These relay series are designed for demanding rolling stock applications. The RC-19A is used in applications for current monitoring or earth fault protection.
