Circuit breakers are essential components in any electrical system, providing a way to protect circuits from damage caused by power surges, overloads and short circuits. R11-4-20.0A-37088-3 is a circuit breaker, and this article will explain its application field and working principle.

Application field

R11-4-20.0A-37088-3 is mainly used in industrial and commercial power distribution networks, as well as in residential buildings. It is also suitable for mobile and temporary electrical installations. Due to its internal construction and its thermal and magnetic characteristics, it has a wide range of applications, such as protection against short-circuits, against overload and against any type of power surge.

Working principle

This circuit breaker works with both thermal and magnetic forces. The thermal principle involves a heat-sensitive element that opens the circuit if the temperature of the protector exceeds a predetermined level. This protective element is placed between the main contact and a thermally sensitive switch. This switch is connected to a thermal relay that is in turn connected to a heater coil. When the current travels through the coil, it generates heat, which is then transferred to the thermal relay, causing it to open and disconnect the circuit.

The other process involved in the operation of this circuit breaker is the magnetic field principle. It involves the use of an electromagnet that becomes activated when there is an excessive current. The electromagnet forms an arc which opens the main contacts and thus discontinues the current flow. This process is very fast and prevents further damage and potential fire hazards.

In summary, the R11-4-20.0A-37088-3 circuit breaker uses both thermal and magnetic force to protect circuits from damage caused by power surges, overloads and short circuits. It is mainly suitable for industrial and commercial power distribution systems, as well as residential buildings and mobile or temporary installations. It uses a heat-sensitive element, a thermal relay and an electromagnet in order to quickly break the current flow and prevent further damage.
