Slide 4: Principle of Operation

• Principle: A circuit breaker works on the principle of thermal or magnetic tripping.
• Thermal Tripping: The breaker trips when the temperature of the contacts exceeds a certain level.
• Magnetic Tripping: The breaker trips when the magnetic field around the contacts exceeds a certain level.
