Three-Pole Trip Circuit Breaker
The initial settings necessary to enable autoreclose for a single three-pole trip
circuit breaker are shown in Table 4.2.
Single-Pole Trip Circuit Breaker
The initial settings necessary to enable autoreclose for one single-pole trip
circuit breaker are shown in Table 4.3.

The SELOGIC control equations E3PR1 and ESPR1 set the relay for the
autoreclose modes. Table 4.4 illustrates how to enable the autoreclose modes
for Circuit Breaker 1.
