2-pole, 63-amp AC circuit breaker is a safety device that protects electrical circuits from overcurrents in AC systems. It's designed for two-wire circuits (typically live and neutral) and can handle a maximum current of 63 amps. The "2P" signifies it's a double-pole breaker, meaning it simultaneously disconnects both the live and neutral wires, ensuring complete circuit isolation during faults. These breakers are commonly used in residential, commercial, and industrial settings. Key Features and Functions: Current Rating: 63 amps, indicating the maximum current the breaker can safely handle. Double Pole (2P): Simultaneously disconnects both the live and neutral wires, providing enhanced safety. Overload Protection: The breaker trips (opens the circuit) when the current exceeds the rated 63 amps, protecting against damage from excessive current flow. Short Circuit Protection: Reacts rapidly to short circuits, preventing potential fire hazards and equipment damage. AC Voltage Compatibility: Suitable for standard AC voltage systems (e.g., 120V, 240V, or 415V). DIN Rail Mountable: Designed for easy installation on standard DIN rails in electrical panels. Thermal-Magnetic Trip Mechanism: Often utilizes both thermal and magnetic elements to detect overloads and short circuits, respectively. Application: Suitable for various applications, including lighting systems, appliances, and machinery.
