Insulation class Defines the type of device insulation in terms of earthing and the corresponding safety for user, in one of three classes.
Class I. The device is earthed. Any electrical faults, internal or external, or caused by the load, are cleared via the earthing circuit, thus ensuring user safety.
Class II. The device is not connected to a protective conductor. User safety is ensured by reinforced insulation around the live parts (an insulating case and no contact with live parts, i.e. plastic buttons, molded connections, etc.) or double insulation.
Class III. The device may be connected only to SELV (safety extra-low voltage) circuits. The ComPact NSX are class II devices (front) and may be installed through the door in class II switchboards (standards IEC 61140 and IEC 60664-), without reducing insulation, even with a rotary handle or motor mechanism module.
