Circuit Breakers

Circuit breakers are devices used to interrupt and interrupt current flow in a circuit. This type of device is used to protect an electrical circuit from overloads or short circuits that may otherwise cause excessive damage and lead to fire or other catastrophic events. Circuit breakers are typically rated in amperes, meaning that they must be able to safely conduct and break electrical current at the given rating for the circuit breaker. Circuit breakers are typically connected to a control circuit of some sort, such as an AC or DC power source.

4429.0003 Application Field and Working Principle

The 4429.0003 circuit breaker is an off-the-shelf UL 489 listed Module Type device designed to offer performance, safety and versatility for a wide range of applications. The 4429.0003 is rated for voltages up to 480 VAC and nominal current ratings of 5 Amps to 60 Amps, with an operating range between 4 to 70 Amps. This device is designed with a modular body, providing a space-saving design, easy wiring and installation, and lower cost of ownership.

The operating principle of the 4429.0003 is that when the current in the circuit exceeds the breaker’s rating, it causes the contacts to separate, opening the circuit and interrupting the current. This interruption protects the circuit and current from damage. The 4429.0003 also has a manual tripping mechanism that allows the user to manually reset the breaker, if necessary. The tripping mechanism is also designed to trip if the temperature of the circuit reaches an unsafe level or if the circuit senses a short circuit.

The 4429.0003 circuit breaker is designed for use in residential, commercial and industrial applications. It also provides superior protection from short-circuits, over-loading, and overheating, which helps ensure the safety of the circuit and operation of the electrical equipment. Additionally, these circuit breakers can be applied to applications with both AC and DC loads.

Because the 4429.0003 is UL 489 listed, it meets the requirements of the National Fire Protection Association (NFPA) and Underwriter\'s Laboratories (UL). UL testing confirms that the circuit breaker will open if the circuit passes a specified current, meaning that it is safe for use with all types of electrical circuits. Additionally, it is designed with a trip-free operation and lockout features, providing an extra layer of safety.

Overall, the 4429.0003 circuit breaker is a reliable and versatile way to protect a variety of circuits. With its UL 489 listing, a wide range of ratings, and advanced safety features, the 4429.0003 is an excellent choice for protecting any circuit. It is reliable, easy to install, and less likely to malfunction than many other circuit breakers on the market.
