Mechanical status indicators The following are the possible states in which you can find the circuit-breaker:
1. Circuit-breaker open with springs discharged (see Figure 48).
2. Circuit-breaker open with springs charged (see Figure 49).
3. Circuit-breaker closed with springs discharged (see Figure 50).
4. Circuit-breaker closed with springs charged (see Figure 51). This state occurs when after closing (see
step 4 - Figure 51) the springs are recharged manually or automatically by the gearmotor (if provided).
