The LA070URD31KI0400 is an UL Recognized, CSA Certified and VDE Approved, Non-Recoverable Fuse. It is a Circuit Breaker Trip Unit with an operating current of 70A. As a specialty fuse, its application field can be used in a wide range of electrical systems and the corresponding working principle of this component is relatively simple.

This non-recoverable fuse type provides superior ultra-fast cycling capability along with steady state overload protection. It is designed to break the circuit before its protection element (fuse) melts and opens. This type of circuit breaker is quite versatile as it can be used in both AC and DC applications. It is the ideal solution for protecting loads in industrial, commercial and residential applications.

LA070URD31KI0400 provides excellent protection against transient vibrations and power surges. Moreover, its construction does not require the use of capacitors, resistors or thermistors like other low-level circuit breaker types. It is also highly resistant to the effects of humidity and shock. This determines its longevity and reliability in the most extreme conditions.

The working principle of the non-recoverable fuse is based on the difference between the capacity of the fuse and the operational current. When the current of the connected load exceeds the rated current, the fuse will be damaged and the circuit will be interrupted in order to protect the component from further damage. This is why the fuse works as an overload protection device.

Unlike other fuse types, the LA070URD31KI0400 has an additional feature of being weatherproof. This makes it suitable for outdoor applications in wet and humid environments. Additionally, this type of fuse does not require careful installation, as long as its terminals are properly connected.

In conclusion, LA070URD31KI0400 is an ideal specialty fuse for a wide range of electrical applications, particularly those that are exposed to harsh environments. It is reliable and provides excellent overload protection. Its simple working principle makes it an economical, reliable and dependable device for protecting circuit breakers from heavy overload or power surges.
