Buy Chint MCCB from IRAN
The automatic Chint circuit breaker protects against overload currents by disconnecting via a temperature-sensitive component when triggered by excessive heat. The functionality of the Chint representation circuit breaker essentially involves the contact of two metals that expand at different rates under high temperatures. This circuit allows the two metal contacts to touch, allowing electrical current to pass through the automatic switch. When the current exceeds a certain threshold, the heat-sensitive contacts begin to heat up and bend due to differential thermal expansion, thus disconnecting the electrical current.

Reasons for using Chint automatic switches:
Chint automatic switches are used to protect downstream consumers in the electrical input and output currents of electrical distribution panels. The Chint automatic switch has a lever that can be in three positions. In the first position, which is done with manual force, it is in the connected state. In this position, the switch lever moves upwards, and a mechanical indicator in red appears, indicating that the switch is connected. The second position is the off position, which is done manually. In this position, the switch lever is at the lowest point, and its mechanical indicator appears in green. The third position is the result of the operation of the thermal or magnetic mechanisms of the switch. In this position, the switch lever is in the middle position. After checking and troubleshooting the electrical installations, in this position, we should move the switch lever downward or to the off position and then press the lever upward or to the on position.
Function of Chint automatic switches:
Chint automatic switches have overload protection and short-circuit protection and are essential components in distribution panels. The rated current of this Chint switch ranges from 25 to 1600 amperes and has 3 poles with suitable breaking capacity. This automatic switch can be installed horizontally or vertically in its place using screws. Additionally, there is a small button on the Chint switch to test its internal protective mechanism, which, when pressed, switches the switch to the TRIP state.
