摘要:
A current-limiting device is provided with pressure relief facilities that are responsive to relieve internal pressured during operation of the current limiter. In a specific arrangement, the pressure relief arrangement includes a passage that is opened upon operation of the current limiter to communicate between the interior and the exterior of the current limiter. The passage includes a fusible material therein that is melted by the heating within current limiter under predetermined high-current fault conditions. In a specific arrangement, the passage is formed through a contact terminal of the current limiter. In one arrangement, the current-limiting device includes an adjoining exhaust section and the contact terminal extends into the adjoining exhaust section.
