Egis Mobile Electric Battery Disconnect Switches: Engineered for Demanding Environments
Egis Mobile Electric has built a reputation as a go-to manufacturer for mobile electrical solutions in some of the toughest conditions on water and land. Their battery disconnect switches are a prime example of that philosophy — purpose-built to isolate, protect, and control battery systems in marine vessels, fleet vehicles, RVs, and off-road equipment where electrical reliability is non-negotiable.
The XD Series: A New Standard in Battery Disconnect Technology
At the heart of Egis Mobile Electric's disconnect switch lineup is the XD Series, a family of heavy-duty mechanical contactors and remote battery switches rated up to 500 amps. Unlike traditional rotary-style switches, Egis XD Series battery disconnects use an advanced bi-stable solenoid design that delivers a significant reduction in mounting space and product weight compared to conventional solutions.
The XD Series is designed with flexibility in mind. Each unit can be configured via dip switches to function as a standard battery disconnect relay, a voltage sensing relay, or a low voltage disconnect — adapting to a wide variety of system requirements without additional hardware. Remote ON/OFF/Auto inputs allow forced open or close states, or fully automatic operation based on voltage sensing, giving installers and end users precise control over their battery systems.
Built Tough — Sealed, Durable, and Expandable
Egis XD Series disconnect switches are sealed to IP67/IP6K9K ratings, using high-temperature electronics and materials that allow mounting virtually anywhere aboard a vessel or vehicle. Silver alloy electrical contacts support high-ampere, full-voltage switching without degradation over time — a key advantage in high-cycle applications. A Gore-Tex vent regulates internal device pressure to eliminate moisture intrusion, further extending service life in harsh environments.
One of the most compelling aspects of the XD Series is its modular, expandable architecture. Using optional Link and CrossLink busbars (the 8790 and 8791 accessories), installers can integrate a single XD battery disconnect directly with XD Series Flex, ACR, and Low Voltage Disconnect relays — supporting two- or three-battery systems from one unified, compact footprint. This interconnectivity dramatically simplifies wiring, eliminates external link cables that could vibrate loose, and reduces overall installation cost.
Mini Breaker Disconnect Switches: Compact Circuit Protection
Beyond the flagship XD Series, Egis Mobile Electric also offers Mini Breaker Disconnect Switches — panel-mount solutions that combine automatic circuit protection with manual on/off switching in a single compact unit. These are ideal for branch circuit isolation and load circuit maintenance, and are sealed against dust and water intrusion for long-term reliability anywhere in a mobile electrical system.
Who Are Egis Battery Disconnect Switches For?
Whether you're a marine electrician building out a complex multi-battery system, an RV owner protecting your house bank, or a fleet manager maintaining commercial vehicles, Egis Mobile Electric's battery disconnect switches offer a level of engineering precision and real-world durability that sets them apart. Their designs are also plug-and-play compatible with many legacy competitor products, making upgrades straightforward without rewiring entire systems.
