Circuit breakers are an essential part of modern electrical systems, and 9101403200 is a model of circuit breaker, manufactured by GE. It is used to monitor and control the electrical current of the system, preventing unsafe, excessive current conditions and automatically breaking the circuit in case of a fault. This article will describe the application field and the working principle of model 9101403200.

Application Field of 9101403200

Circuit breakers of model 9101403200 provide voltage and current protection for industrial and power applications, such as control panels, bus-way, switchgear, transfer switch and generator applications. They are also suitable for use in residential, commercial and industrial buildings to protect against circuit overloads. The 9101403200 is designed to suit the requirements of National Electrical Manufacturers’ Association (NEMA) standard ANSI C37.01. This model is designed to operate in temperatures between -40 ˚C and +85˚C and pressures up to 12 kilopascals. The 9101403200 can be incorporated in three-phase, four-wire and three-pole designs and can be used in systems up to 38kV voltage and 1000A current.

Working Principle of 9101403200

The 9101403200 operates in a three-pole single-throw manner to protect the connected electrical components from a high current overload. The operation of this circuit breaker is based on the Joule heating effect. When the current passes through a wire, it generates heat that can damage the wire and other components in the circuit. To prevent this, the circuit breaker will open the circuit when the current rises above a set point to interrupt the current.

The 9101403200 uses a thermal-magnetic trip system that combines both a thermal element and a magnetic element. The thermal element senses the temperature of the circuit breaker caused by the flow of current and responds, while the magnetic element senses the instantaneous current flow and responds with a set point that is higher than the thermal element. This makes sure that the circuit breaker will open before any damage to the components in the circuit occurs. The 9101403200 also has an adjustable tripping range that can be adjusted to suit the requirements of the system.

The 9101403200 model can be used to protect high-voltage circuits as well. It has trip ranges of 1.3—3.9 times of the rated current, and it can be used to protect circuits up to 38kV voltage and 1000A current. The 9101403200 offers continuous protection against not only overload but also short-circuits, under-voltage and phase reversal.

In conclusion, the GE 9101403200 is a great choice for applications that require protection from high currents or likelihood of short-circuit. It has wide operational range, decent current sensitivities and can be adjusted to match the requirements of the system. Its trip mechanism uses both a thermal element and magnetic element to ensure protection of the components in the circuit.
