Trinetics® RCOC® Street Lighting Control Relays - MTR Series

The MTR Series is designed for users who prefer mercury tube contactors that are hermetically sealed and have no contactor wear points, no-spark operation and only one moving part.

The single moving part is a ceramic plunger that causes mercury to flow together or separate to electrically close and open the load circuit. The ruggedness and reliability of this simple design have been proven in thousands of field applications. The MTR Series is available in the following standard versions:

One or two pole

Normally open or normally closed

30, 60 or 100 amp
