Product Description
Gigavac HBD41AA 400A Manual Disconnect Switch
GIGAVAC HBD41AA Manual Battery Disconnect - 400A 1000VDC
The **GIGAVAC HBD41AA** is the high-capacity flagship of the HBD series, providing a revolutionary manual power isolation solution for systems up to **1000VDC**. Engineered for heavy-duty applications, it delivers a massive **400A** continuous carry current in a compact 400g package. Unlike traditional open-frame switches, the HBD41AA is **hermetically sealed**, exceeding IP69 standards to ensure that internal arcing is contained and contacts are permanently protected from oxidation. This makes it the premier choice for hazardous locations, mining equipment, and high-performance electric vehicles where safe, manual disconnection under extreme environmental conditions is a critical safety requirement.
