Abstract
A gap-type surge absorbing element and a varistor are assembled end to end in an insulating tube to form a compact surge absorber. Electrodes on the two devices contact a intermediate element to provide electrical connection therebetween. End electrodes seal the insulating tube and provide external connection to the outboard ends of the two devices, thereby putting them in series. The interior of the insulating tube is filled with an inert gas. Embodiments are described using microgap-type and gap-type surge absorbing elements.
