Time element relay is coded as which?

Explanation:
In this coding scheme, a time element relay is identified by adding a suffix that signals timing or delay to the base relay symbol. The base letter U represents a relay, and the r suffix stands for retardation (delay). Together, Ur denotes a relay with a time-delay function. The other forms either lack the timing indication or imply different, non-time-delay functions, so they aren’t used to represent a time element relay.
