Circuit breakers are an integral part of electrical systems, protecting circuits from extreme overloads and short circuits. They do this by automatically disconnecting an electrical circuit when current flow exceeds its safe limits. The IELCBXK1-35558-1-V is a low-voltage circuit breaker with a variety of applications and a unique working principle.

Applications

The IELCBXK1-35558-1-V is a low-voltage circuit breaker that is ideal for use in residential, commercial, and industrial applications. In residential applications, it is commonly used to protect home electrical systems from overloaded and short-circuit damage. In commercial applications, the breaker can be used to protect large electrical systems such as office and retail buildings, where a large number of electrical appliances and electronic devices are typically present. It is also commonly used in industrial applications such as manufacturing, food and beverage, and other facilities that require frequent machinery operation.

Working Principle

The IELCBXK1-35558-1-V low-voltage circuit breaker uses a thermal-magnetic element in its design to provide added protection against both thermal overloads and short circuits. It also makes use of a specially designed system that trips the circuit breaker at a predetermined amperage. The system includes a bimetallic strip, a thermal trip mechanism, a magentic trip mechanism, and a common trip mechanism.

The bimetallic strip is installed in the breaker and serves to detect current that exceeds the thermal trip threshold. When the ambient temperature is at or below room temperature, the strip remains in its normal state and allows the flow of current into the circuit. However, if the temperature of the bimetallic strip increases due to an increase in current flow, the strip begins to bend and opens the circuit breaker.

The thermal trip mechanism works in conjunction with the bimetallic strip to further protect the circuit from thermal overloads. The thermal trip mechanism is designed so that current flow is cut off before the temperature of the bimetallic strip exceeds a set level. This is accomplished by a pre-primary current sensing coil and a relay switch. The sensing coil detects changes in current flow and sends a signal to the relay switch which trips the circuit breaker and prevents excessive temperatures.

The magnetic trip mechanism is a safety feature that works by detecting any increase in the current flow beyond a certain amp rating. This mechanism is activated through the use of a sensing core to detect changes in the current flow and a trip coil to activate the circuit breaker and open the circuit.

Finally, the common trip mechanism is the fourth protection feature of the IELCBXK1-35558-1-V circuit breaker. This mechanism is used to trip the circuit breaker whenever there is an overload on multiple connected circuits or a short circuit in one circuit that affects the other circuits. This is accomplished through the use of a separate sensing coil that receives signals from all connected circuits and causes the trip coil to activate the circuit breaker and open the circuit if any overload or short circuit are detected.

Conclusion

The IELCBXK1-35558-1-V is a low-voltage circuit breaker with a variety of applications and a unique working principle. It is designed with a thermal-magnetic element to provide added protection against both thermal overloads and short circuits and is commonly used in residential, commercial, and industrial applications. The breaker also features four protection features that trip the circuit breaker at a predetermined amperage, provide further protection against thermal overloads and short circuits, detect any increase in current flow beyond a set amp rating, and trip the circuit breaker whenever there is an overload on multiple connected circuits or a short circuit in one circuit that affects the other circuits.
