Information about the LÜTZE LOCC-Box-EC I-C3-0350

The LÜTZE LOCC-Box-EC I-C3-0350 sets a high standard for selective electronic load monitoring in 12 V and 24 V DC industrial systems where dependable circuit protection within minimal space is required. Its standout feature is its ultra-slim profile width of just 8.1 mm, saving valuable space on the TS35 DIN rail inside the control cabinet without sacrificing protective features. This model delivers a fixed rated current of 3 A with a slow tripping characteristic (C3 / slow-1), handling heavy inrush capacitive loads of up to 10,000 µF without unwanted tripping. Operating seamlessly within a flexible working voltage range of 10 V to 30 V DC, it integrates a screwless disconnect slider and copper busbar feed to support power supply currents up to 40 A.

Beyond selective tripping during overload or short-circuit events, this load monitor utilizes a durable MOSFET switching output with minimal voltage drop to keep power loss extremely low. Dual LED status indication (Green/Red) together with an integrated transistor signal output allows immediate local troubleshooting and direct feedback to high-level controllers (PLCs). Its vibration-proof spring-clamp terminals ensure stable wiring in ambient temperatures ranging from -25 °C to +50 °C, while full compliance with international industrial standards like cULus, EN 61131-2, and EN 60947-4-1 ensures safe operation. This engineering quality and system reliability are supported by a full 3-year manufacturer warranty for optimal peace of mind.
