Abstract
A varistor component and a method for securing a varistor component are disclosed. In an embodiment, a varistor includes a first external contact, a second external contact, a varistor electrically connected to the first external contact, a path between the varistor and the second external contact and an active releasing device including a shutter and a heat sensitive element, wherein the heat sensitive element releases the shutter under abnormal operation conditions and the shutter closes the path between the varistor and the second external contact.
