Circuit breakers are a type of electrical safety device that is designed to protect electrical circuits from possible damage due to overloads or short circuits. They are commonly used in residential and commercial installations, such as in homes and businesses, to prevent power overloads or surges from reaching the electrical wiring and ultimately, the appliances connected to the circuits. The 1140-G151-P7M1-018803-1A circuit breaker is a 3-pole, dual-function device with a rated current of 30A and a rated voltage of 240V that is used to protect the circuit from short-circuits and overloading.The 1140-G151-P7M1-018803-1A circuit breaker is a type of molded case circuit breaker (MCCB). MCCB’s are generally used in industrial applications as they are capable of providing reliable mechanical strength and electrical continuity. It also typically offers better performance in terms of current interruption, dynamic performance, electrical contact stability, and thermal protection. The 1140-G151-P7M1-018803-1A circuit breaker is typically used in commercial and industrial settings that require reliable interrupting performance and current protection for 120/240V AC circuits.The general working principle of the 1140-G151-P7M1-018803-1A circuit breaker is fairly straightforward. Its tripping system is designed to detect any overcurrent situation and initiate the tripping mechanism. This is done by detecting changes in the current passing through the breaker. When the current rises above a certain level, the breaker senses the overload and trips, thereby preventing any further damage to the circuit. This process occurs almost instantaneously and without any human intervention.The 1140-G151-P7M1-018803-1A circuit breaker also provides thermal protection through its thermal-magnetic tripping device. This device is designed to monitor the temperature of the circuit, and in the event of the temperature exceeding a certain level, it trips the circuit, preventing any further possible damage. The 1140-G151-P7M1-018803-1A circuit breaker also has a manual enable/disable switch, allowing it to be switched off in the event of maintenance or other necessary circuit repairs.The 1140-G151-P7M1-018803-1A circuit breaker can be used to protect many different types of electrical circuits. It is commonly found in commercial and residential applications, such as homes and businesses, to protect against power overloads, short-circuits, and surges. It is also used in industrial applications to protect machinery, motors, and transformers from over-current or short-circuiting.In summary, the 1140-G151-P7M1-018803-1A circuit breaker is a 3-pole, dual-function device that is used to protect electrical circuits from damage due to overloads or short circuits. It utilizes a thermal-magnetic tripping device to detect overcurrent situations and initiate the tripping mechanism. The manual enable/disable switch makes it suitable for use in many different applications, including industrial and residential settings.
