The Schneider Electric LPJ225SP is a delay fuse, engineered to offer dependable protection against overcurrent scenarios. With a substantial amperage rating of 225 A, this fuse is adept at handling voltages reaching 600 V AC and 300 V DC. It can interrupt potentially damaging currents with a high capacity of 300 kA at 600 V AC and 100 kA at 300 V DC, making it effective in various electrical environments.
The time response characteristic of the LPJ225SP indicates that it operates with a time delay, allowing for a response time of greater than or equal to 10 seconds when subjected to currents at 500% of its rated value. This function is essential for protecting circuits during temporary overloads where an immediate disconnection is unnecessary. The fuse also features an inverse time-delay trip characteristic, providing additional flexibility in its operation.
Constructed with dual-element technology, the LPJ225SP incorporates both thermal and magnetic elements to enhance its fault detection capabilities. As a non-indicating fuse, it does not provide visual feedback on fault conditions, relying instead on its functional characteristics to enact protection. Connecting to terminals is accomplished via bolted blade contacts, ensuring secure and reliable connections.
In terms of size, the fuse measures 7.13 inches in length, 2 inches in width, and 2 inches in height, fitting within compact installations. With a total weight of 1.5 pounds, it is manageable for handling during installation. The fuse mounts in a holder style, making it straightforward to integrate into existing systems. This combination of features makes the LPJ225SP a vital component in protection systems for various industrial and commercial applications.
