Circuit breaker is generally composed of make contact with method, arc extinguishing system, functioning mechanism, tripper, housing and so on.
The main characteristics of circuit breaker are: rated voltage Ue rated recent In location range of tripping current for overload safety (Ir or Irth) and limited circuit safety (Im) rated brief circuit breaker existing (Icu for industrial use Icn for family use).
one.Auxiliary contacts: contacts that are mechanically linked with the major circuit dividing and closing mechanism of a circuit breaker. They are mostly employed for exhibiting the dividing and closing states of a circuit breaker. They are related to the handle circuit of a circuit breaker and are managed or interlocked by the circuit breaker.
2.Alarm contacts: Alarm contacts for circuit breaker mishaps, and this contact only when the circuit breaker trips off and breaks, mainly for the load of the circuit breaker overload limited circuit or undervoltage and other faults and free tripping, alarm contacts from the original standard open place to the closed position.
3.Excitation tripper: Excitation tripper is a variety of tripper pushed by a voltage supply. Its voltage has nothing at all to do with the voltage of the main circuit. Excitation tripper is an accent for prolonged-length procedure of swap-off.
4.Undervoltage tripper: Undervoltage tripper is a tripper that causes circuit breakers to open up with or without having delay when its terminal voltage falls to a specified assortment.
5.Electric Operator: This is an accent for remote automatic switching and closing circuit breakers.
6.Prolonged manage: It is an exterior extended manage directly mounted on the manage of circuit breaker. It is generally used on large capacity circuit breakers of 600A and earlier mentioned for handbook switching-off procedure.
seven.Manage locking system: a clamp is set up on the deal with frame, punched on the deal with, and then locked with a padlock. Largely utilised for closing circuit breaker.
