A Circuit Breaker is used for disconnecting the power supply during overload. When the current flowing through the circuit exceeds the breaker's rated capacity, the internal mechanism of the single pole circuit breaker trips, opening the circuit and stopping the flow of electricity. This action effectively protects the circuit and connected devices from damage due to excessive current.

Attributes:
• Able to reset after tripping, providing a convenient and reusable method of circuit protection
• Manufactured to precise specifications and is built for durability and reliability

Applications:
A Circuit Breaker interrupts the flow of electricity when an overcurrent condition is detected, preventing potential hazards such as fire or damage to electrical equipment.
