type ACB Air circuit breaker Circuit breaker is
generally composed of contact system, arc extinguishing system,
operating mechanism, tripper, housing and so on. The main
characteristics of circuit breaker are: rated voltage Ue; rated
current In; setting range of tripping current for overload
protection (Ir or Irth) and short circuit protection (Im); rated
short circuit breaker current (Icu for industrial use; Icn for
household use). 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. mechanical interlocking contactor Specification Type
