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 49).
2. Circuit-breaker open with springs charged (see Figure 50).
3. Circuit-breaker closed with springs discharged (see Figure 51).
4. Circuit-breaker closed with springs charged (see Figure 52). This state occurs when after closing
(see step 4 - Figure 52) the springs are recharged manually or automatically by the gearmotor (if
