Carlisle IntelliSpray Circuit Breaker 15A/3P C Trip

A circuit breaker is a device that protects electrical circuits from overcurrents by interrupting the flow of electricity when a fault is detected. A circuit breaker has three main components: a fixed contact, a moving contact, and a trip unit. The fixed and moving contacts are normally closed, allowing electricity to pass through. The trip unit is a mechanism that senses the current and opens the contacts when the current exceeds a certain level. There are different types of trip units, such as thermal, magnetic, or electronic, that respond to different types of faults.
