The invention relates to a high-voltage electrical device, such as a voltage sensor (10) or a circuit breaker. The high-voltage electrical device comprises an insulating body (12), an electronic device (13) insulated by the insulating body (12), and a safety device (23) for discharging a gas over-pressure out of the electrical device when an arc is formed. The insulating body (12) comprises a hollow body (18) in which the electronic device (13) is located and a housing (19) covering the hollow body (18). The housing (19) is made of a material that is softer than the material of the hollow body (18). The safety device (23) is located within the insulating body (12) opposite the housing (19) and is arranged to allow gas over-pressure to locally open the housing (19) to avoid equipment out-of-control explosion.
