LOCC Box DC Electronic fuse for 24V dc circuits, NEC Class 2

LÜTZE LOCC-Box module was specially developed for load circuits in compliance with NEC Class 2. The UL-defined circuits are limited to 100 VA and, thanks to the energy limit, are protected against electrical shocks or fire. As a Class 2 load current monitoring system, it is now possible to supply standard switching power supply units. In addition, components that are not UL-approved can also be used in the load circuit. In contrast to other Class 2 load monitoring systems, LÜTZE's LOCC Box has configurable characteristics and current ranges.

There are 3 characteristics (fast, medium and slow_1) available for the new Class 2 module. These current ranges can be set with a rotary knob from 0.5 A to 4 A in 0.5 A steps.

Green and red LEDs in the LED status display indicate operating voltage and errors in the load circuit. In addition to current limitation in compliance with NEC-Class 2, the DC 24 V / 100 VA load monitoring also satisfies the standards EN 60950-1, EN 61131-1,2, EN 61000, EN 60947-4-1 and EN 55022.
