Eight different MICO modules are now NEC Class 2 approved, so you can efficiently design your power distribution scheme.
Class 2 Circuits are circuits with limited energy and a maximum power of 100VA. According to the NEC & UL definition, class 2 circuits limit the risk of electrical fires and electric shocks due to their limited energy. Therefore, according to UL508A standard (for control cabinets), components used on the branch circuit in a Class 2 circuit don’t require investigation.
Hitherto, an individual NEC Class 2 approved power supply was used to create a class 2 circuit and it required a lot of space. This method wasn't cost effective and involved a lot of wiring and planning effort.
With Murrelektronik's MICO NEC Class 2 approved module, it is now possible to design NEC Class 2 circuits even faster, in a more compact and cost effective way. All you need is a standard power supply unit (that doesn't necessarily has to be NEC Class 2 approved) combined with MICO to design two, four or eight separate load circuits with limited energy in a simple way.
By connecting several MICO modules with the integrated bridging system, the number of channels can be increased up to a total current of 40A. Components attached to the MICO’s marked NEC Class 2 outputs devices no longer need UL-approval.
MICO's proven functions like channel-specific switch-off in case of overload, visual warning notice, storing errors and the cascading start of the current paths provide additional benefits and enable using a smaller power supply and limit the operators need to enter the control cabinet.
