Circuit breaker accessory

5.1 Internal accessory
5.1.1 Shunt release
Connection diagram, see Fig 1 an Fig 2.
Rated voltage of control power supply: AC 50/60Hz, 230V, 400V; DC24V, circuit breaker can operate reliably under 85% to 110% of the rated control power supply voltage.

5.12 Under-voltage release
When the voltage is below 35% of the rated control power voltage, this release can prevent circuit breaker against closing. Connnection diagram, see Fig 3.
When the voltage decrease to the range of 70% to 35% of rated control power voltage, the under-voltage release would trip.
When the voltage is in the range of 85% to 110% of the rated control power voltage, this release can ensure the circuit dosing reliably.
Notice: The circuit breaker with under-voltage release could trip and close, only supplied the circuit breaker with rated voltage.

5.13 Auxiliary contact
circuit breaker has two sets contact,each set is not open on electric, the auxiliary contact details, see Table 5.

5.14 Alarm contact

5.15 Special circuit breaker accessories of Pre-paid meter
Shunt release of Pre-paid Meter rated operational voltage is AC230V 50Hz, Operate in the range of 65% to 110% Ue,when the Ctrl point is open, circuit breaker will be break after 0.5s to 2s deley. See Diagram：

5.16 Over-voltage circuit breaker
Over-voltage circuit breaker should be tripping under following conditions:
a) When the rated operational voltage(phase voltage)Ue lower than 262V
b) When the neutral line of three phases and four wires is breaking
c) When the neutral line misconnecting phase lines,
