4404.0005

Circuit breakers are control devices that protect electrical systems and components from damage caused by excessive current, usually resulting from a power surge or overheating. The 4404.0005 is an advanced circuit breaker designed for a variety of applications due to its superior safety ratings and increased protection levels. In this article, we’ll discuss the 4404.0005’s application field and working principles.

The 4404.0005 circuit breaker is a great choice for residential and industrial wiring applications. It is suitable for use in AC circuits with a power rating of up to 5kVA. Thanks to its safety rating of 50kA, the 4404.0005 is the ideal choice for the more demanding power protection requirements. It also features an adjustable trip setting and an integrated thermal-magnetic trip device for enhanced protection.

The 4404.0005 circuit breaker also offers some unique features for increased safety. First, its UL 489 listing ensures that it is compliant with all applicable safety requirements. Additionally, it offers an automatic reset after a fault, and its high-visibility terminal blocks provide easy access to both the six and twelve pole terminals. This makes it easy to inspect and maintain the circuit breaker, while also ensuring that it remains safe and in compliance with all applicable rules and regulations.

The 4404.0005 circuit breaker achieves its superior safety ratings thanks to its working principle. It uses both a thermal-magnetic trip and a current sensing device to detect any overloads. If an overload occurs, the thermal-magnetic trip instantly shut off the circuit, while the current sensing device will open up the circuit, thus preventing any further damage. This combination increases the safety threshold and allows the circuit breaker to provide more reliable protection.

In addition to the thermal-magnetic trip, the 4404.0005 also has an adjustable current-sensing trip point which is used to increase the safety threshold in certain applications. This adjustable trip point is what allows the 4404.0005 circuit breaker to meet UL 489 and other safety standards, while also providing reliable protection in more demanding applications. The adjustable trip point also ensures that the circuit breaker can be used in purposes other than just providing power protection.

In conclusion, the 4404.0005 circuit breaker is a reliable and safe choice for a range of residential and industrial wiring applications. Its UL 489 listing and adjustable current-sensing trip point ensure that it can handle a variety of power demands, while its thermal-magnetic trip and current sensing device provide enhanced protection from overheating and power surges. The 4404.0005 circuit breaker is the perfect choice for any application requiring a safe and reliable control device.
