The Schneider LV432080 is a sophisticated trip unit designed for seamless integration with Compact NSX 630 circuit breakers. This electronic device, rated at 630 A and suitable for systems up to 690 V AC, is engineered to provide reliable protection and efficient distribution management. It features a three-pole configuration and is equipped with the Micrologic 2.3 technology, ensuring precise protection for electrical circuits.
The LV432080 trip unit offers a range of adjustable settings to cater to various protection needs. It includes long-time protection with nine adjustable settings for current pick-up, ensuring thermal protection tailored to your system's requirements. The fixed delay adjustments for long-time protection delay offer a range of settings to suit different applications, from heavy-duty machinery to sensitive electronic equipment.
Short-time protection is also adjustable, with a pick-up adjustment range that can be set from 1.5 to 10 times the rated current, providing flexibility in managing short-circuit conditions. The fixed delay for short-time protection ensures rapid response to transient faults, minimising potential damage.
For immediate threats, the LV432080 features a fixed instantaneous protection pick-up adjustment, capable of handling currents up to 6900 A. This rapid response is crucial for protecting equipment from sudden and severe short-circuit events.
The unit's thermal memory spans 20 minutes before and after tripping, allowing for a more informed analysis of the circuit conditions leading up to and following a trip event. This feature is particularly useful for troubleshooting and improving system reliability.
Designed to meet international standards, including UL 508 and EN/IEC 60947-2, the LV432080 trip unit is certified for global use, with additional certifications such as CCC, Marine, and EAC. It operates reliably within a wide ambient temperature range, ensuring consistent performance even in extreme conditions.
The Schneider LV432080 trip unit is a robust and versatile component, essential for modern electrical distribution systems that demand precision, adaptability, and unwavering protection.
