Product Description
Gigavac HBD31AA 300A Manual Battery Disconnect
GIGAVAC HBD31AA Manual Battery Disconnect - 300A 1000VDC
The **GIGAVAC HBD31AA** is a high-power, hermetically sealed manual battery disconnect switch engineered for high-voltage systems up to **1000VDC**. Unlike conventional manual switches, the HBD series features a unique hermetic seal that exceeds IP69 standards, preventing contact oxidation and containing any potential arcing within a sealed chamber. Rated for a continuous carry current of **300A**, the HBD31AA provides a robust and reliable safety interface for heavy equipment, electric vehicle service points, and large-scale energy storage. Its position-insensitive design and extreme temperature resilience make it an essential component for demanding industrial, military, and marine power applications.
