Single-phase earthing fault protection characteristic Single-phase earthing fault means the metal-property earthing protection when fault current exceeds several hundred amperes, which is generally applied
1.Auxiliary contacts: contacts that are mechanically connected with the main circuit dividing and closing mechanism of a circuit breaker. They are mainly used for displaying the dividing and closing states of a circuit breaker. They are connected to the control circuit of a circuit breaker and are controlled or interlocked by the circuit breaker.
2.Alarm contacts: Alarm contacts for circuit breaker accidents, and this contact only when the circuit breaker trips off and breaks, mainly for the load of the circuit breaker overload short circuit or undervoltage and other faults and free tripping, alarm contacts from the original normal open position to the closed position.
3.Excitation tripper: Excitation tripper is a kind of tripper driven by a voltage source. Its voltage has nothing to do with the voltage of the main circuit. Excitation tripper is an accessory for long-distance operation of switch-off.
4.Undervoltage tripper: Undervoltage tripper is a tripper that causes circuit breakers to open with or without delay when its terminal voltage falls to a specified range.
5.Electric Operator: This is an accessory for remote automatic switching and closing circuit breakers.
6.Extended handle: It is an external extended handle directly mounted on the handle of circuit breaker. It is generally used on large capacity circuit breakers of 600A and above for manual switching-off operation.
7.Handle locking device: a clamp is installed on the handle frame, punched on the handle, and then locked with a padlock. Mainly used for closing circuit breaker.
