Intelligent Circuit Breaker DW17-1000A Fix Type Air Circuit Breaker
for Switch PanelCircuit 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.
