Scheme 2 (Intermediate)
[dw_7SR5_function74TCSettingExample2, 1, en_US]
Figure 6-13 Trip‑Circuit Supervision Scheme 2 (H6)
Scheme 2 provides continuous trip‑circuit supervision of the trip coil with the circuit‑breaker Open or Closed.
It does not provide pre-closing supervision of the connections and links between the tripping contacts and the
circuit‑breaker and may not therefore be suitable for some circuits which include an isolating link.
Scheme 3 (Comprehensive)

Figure 6-14 Trip‑Circuit Supervision Scheme 3 (H7)
Scheme 3 provides full trip supervision with the circuit‑breaker Open or Closed.
