PELV (English for “Protective Extra Low Voltage” – formerly also known as safety extra-low voltage; see also SELV) describes a voltage that is set so low(extra-low voltage) that there is no danger from body currents in the event of indirect contact or direct contact that does not cover a large area. If insulation fails, there […]
IEC/EN 61140 classifies electrical equipment with regard to safety against dangerous body currents and electric shock. The design features of devices are assigned to the following protection classes: – Protection class 0: No protection. Such devices are not permitted in the European Union. – Protection class I: Device with protective conductor connection and basic insulation […]
