LÜTZE
Lutze's electronic circuit breaker range is being expanded with the new LOCC-Box-Mini. The LOCC-Box-Mini has an integrated negative connection, which makes it very flexible in tight spaces. It has a capacity of 1-8A(1A intervals) and 5 selectable characteristics: Fast (1), Medium (2), slow 1 (3), slow 2 (4), slow 3 (5). It is also adapted for 12/24V DC applications and provides both alarms for tripped fuses with a manual shutdown.
Integrated Negative Connection
The LOCC-Box-Mini has an integrated negative connection which there is a + and - directly on the fuse. This saves both space on the DIN rail and time during installation.
Lutze's Reliable Electronic Circuit Breaker
Lutze offers an electronic circuit breaker for 12 or 24 V DC systems that overcomes issues commonly associated with traditional miniature circuit breakers, particularly over long cable distances and with thin cable cross-sections. Lutze electronic circuit breakers ensure reliable tripping and selectivity without interruptions in unaffected groups. It allows users to adjust the rated current through a thumbwheel under a safety hatch. This adjustment should only be made when the fuse is switched off to prevent electrical hazards.
There are five different characteristics which can be selected to tailor the response to different load conditions, including high inrush currents. Even with the slowest settings the fuse reacts quickly to short circuits compared to a standard miniature circuit breaker.
Adjustable Parameters and Flexible Load Response
For easy connection, the 12 or 24 V DC input can be made directly into each fuse or via a power terminal with a copper rail, which is recommended for installation with multiple fuses mounted close together. A sliding plate mechanism enables easy connection to or isolation from the rail. The circuit breaker can be reset either manually with a button on the front panel or remotely. When a fault occurs, the LED indicator flashes red and when the fault is resolved, it turns solid red. A second reset signal activates the fuse, and the LED lights up green, Also, there is a signal output (open collector) that can be connected to a group providing an alarm in case any fuse in that group trips. The circuit breaker offers a safe system even in the event of electronic failures, thanks to features like a malfunction indicator and internal fuses.
Advanced Features for Safe and Efficient Operation
The signal output from the circuit breaker is an open collector type with a pull-up resistor. It allows for the grouping of fuses and alarms to receive notifications when any fuse in the group trips. The output voltage may vary depending on the external load resistance, Lutze recommends their interface relays for connecting relay coils to the alarm output, ensuring proper function and activation in case of a fault. Additionally, the circuit breaker includes built-in safety features, such as rapid malfunction indicator and an internal fuse to disconnect loads in the event of a short circuit during a fault, ensuring a secure system even during electronic failures.
