The Circuit Breaker is an essential electrical protection device widely used in low-voltage electrical systems. It serves the crucial purpose of protecting circuits and electrical equipment from overcurrents and short circuits. The MCB operates based on the principle of thermal and electromagnetic tripping. When a current higher than the rated value passes through the MCB, it generates heat, causing the bimetallic strip inside the device to bend. This bending action releases the trip mechanism, opening the circuit and disconnecting the power supply. Additionally, an electromagnet operates in parallel to provide a faster trip response during short circuit faults.Attributes:• Designed to operate at a temperature range of -20 to +125°C• Withstands high levels of voltage fluctuationsApplications:The Circuit Breaker is used to provide reliable protection against overloads and short circuits and consists of a tripping mechanism and a toggle switch for manual operation and overload or short circuit occurs, preventing damage to connected equipment.
