Information about the LÜTZE LOCC-Box-FB 7-6401

The LÜTZE LOCC-Box-FB 7-6401 sets a benchmark for electronic circuit protection in industrial environments with its ultra-slim 8.1 mm housing. This electronic load monitoring system provides superior selectivity by detecting overloads and short circuits in DC 12/24 V circuits far more accurately than thermal-magnetic breakers. One of its unique strengths is the user-definable configuration: the rated current can be adjusted via a thumbwheel from 1 A to 10 A in 1 A increments, while five selectable trip curves (ranging from fast to very slow) allow for perfect synchronization with various load types, including high-capacitive loads up to 10,000 µF.

Beyond basic protection, the LOCC-Box enhances system intelligence through a remote status output and control input, facilitating seamless integration into PLC-controlled diagnostics. The maintenance-free spring terminals ensure vibration-proof connections, and the screwless busbar contact system simplifies installation. Utilizing advanced MOSFET technology, the device maintains an exceptionally low voltage drop, which minimizes heat dissipation and improves overall energy efficiency within the control cabinet. This module is the ultimate choice for engineers seeking maximum machine uptime, compact space management, and comprehensive fault monitoring, backed by global standards including cULus and GL certifications.
