Circuit breakers are an important tool in the electrical power grid. They protect electrical installations from overloading and short circuits, both at the home, in the form of fuses and circuit breakers, and down to the distribution level.

The 0902137 circuit breaker is a device that detects and responds to faults in an electrical system. It interrupts the current flow in an overloaded or short-circuited circuit, before damage can occur. The 0902137 is widely used across a variety of industries, including electrical plants and power distribution systems, for both residential and commercial applications.

The 0902137 circuit breaker consists of a terminal box, control contact, trip unit and a trip coil. All parts are housed in a plastic enclosure. The terminal box consists of contact terminals, a power supply connector and a trip unit connection terminal. The control contact is a small switch located on the trip unit. It is the main switch that is open or closed. When it is “on”, the trip unit is enabled and the current flows freely. When it is “off”, the trip coil replaces the control contact and a trip-out is initiated as soon as it reaches a predetermined current limit.

The trip unit is an electronic control unit that includes a thermal or magnetic sensing element, a control switch and a trip coil. The thermal sensing element measures the current flowing through the circuit, while the magnetic sensing element uses the magnetic field around the circuit. The control switch is the main control that opens or closes the breaker. The trip coil is the mechanism that activates the breaker in the event of an overload or trip-out.

The working principle of the 0902137 circuit breaker is as follows. When the current in the circuit exceeds the safe limit, the thermal or magnetic sensing element activates the breaker by breaking the contact between the control contact and the trip coil. This causes the current to be interrupted, preventing an overload or short-circuit. When the current is reduced to safe levels, the control contact reconnects to the trip coil and the breaker is reset, allowing the current to resume.

The 0902137 circuit breaker is an essential component of modern electrical systems. It provides protection against overloads and short circuits, and helps to maintain a safe and efficient electrical system. It is used in residential, commercial and industrial applications to ensure safety, reliability and energy efficiency.
