  2T105 Multi Range Digital Setting Time Delay Relay

  The 2T105 time delay relay is particularly suitable for use in protection & control schemes where precision time delays are required. CB Fail A typical use is for providing a definite time delay in circuit breaker failure protection. For example: The transformer multi-trip relays energize the 2T105 timer & if the circuit breaker (CB) fails to clear the fault within the pre-set (0.6s) the timer times out & operates a…
