Circuit Breakers

Circuit breakers are devices used to safely stop the flow of electricity when a fault or overload current occurs, thereby preventing electrical shock and fire. The device\'s sensing element detects an abnormal current level due to a fault and immediately breaks the circuit by activating a cut-off switch. This minimizes the potential for serious damage to the wiring and equipment in the circuit.

219-3-2600-526 Application Field and Working Principle

The 219-3-2600-526 circuit breaker is used in a variety of applications, including residential, commercial, and industrial settings. It is rated according to the National Electrical Code (NEC) as a Class A (25-200A) circuit breaker. The circuit breaker is designed to protect against short circuits or overloads. It works by using a thermal sensing element, such as a bimetallic strip, to detect an abnormal current level due to a fault or overload condition. The bimetallic strip expands when heated by the abnormal current, causing the contacts of the breaker to open and interrupting the circuit. The thermodynamic properties of the bimetallic strip help control the operational temperature of the breaker, thereby providing additional protection against overheating.

The 219-3-2600-526 circuit breaker also has a manual reset feature, allowing it to be reset in the event of a fault or overload. This allows for the breaker to be reset without turning off the power to the circuit. The breaker is also equipped with a lockout feature, which locks the reset switch in the “OFF” position and prevents the breaker from unintentionally resetting. This is useful in applications where resetting the circuit breaker is not desired, such as in hazardous areas or critical circuits.

The 219-3-2600-526 circuit breaker is a reliable and cost-effective choice for a variety of applications. Its thermal sensing element, manual reset feature, and lockout feature make it an ideal choice for protecting against short circuits and overloads. It is also easy to install and can be used in residential, commercial, and industrial settings.
