Delta Series: Trip, Auxiliary and Supervision


Delta Series: Trip, Auxiliary and Supervision

The Delta relays provides a robust and reliable interface between protection and control system circuits. A more economical alternative to traditional auxiliary, trip and supervision relays, the Delta provides a compact, flexible and high performance solution while meeting relevant IEC standards.
 
A wide voltage range and standard hand reset flag reduces the number of model variations.
 
The Delta range is packaged in a size 2, 2U high case that may be flush panel, rack or rail mounted. A plug in terminal block is provided to allow panel pre-wiring. Where more than 4 contacts are required refer to the Alpha Range Technical Bulletin.
