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 81).
2. Circuit-breaker open with springs charged (see Figure 82).
3. Circuit-breaker closed with springs discharged (see Figure 83).
4. Circuit-breaker closed with springs charged and not ready to close (see Figure 84). This state
occurs when after closing (see step 4 - Manual operations for opening and closing the circuit-
breaker) the springs are recharged manually or automatically by the gearmotor (if provided).
5. Circuit-breaker open with springs charged and not ready to close (see Figure 85). This state occurs
in the following cases:
• The circuit-breaker is open due to tripping of protection trip units and the Reset signal has
not been reset. To close the circuit-breaker press the TU Reset pushbutton on the front of
the circuit-breaker.
• The key lock or padlock is active in the open position.
• The undervoltage coil is de-energized
• The opening coil is permanently energized.
• The closing coil is permanently energized.
• The pushbutton for enabling the insertion/extraction crank of a withdrawable circuit-brea-
ker is pressed.
