EGIS XD Single Mechanical - w/Knob (8710-1900B)
EGIS XD Single Mechanical - w/Knob, 500 A Heavy Duty Battery Switch/Mechanical Contactor (8710-1900B)
The Egis Mobile Electric 8710-1900B (XD Series) is a heavy-duty, compact manual battery disconnect switch and mechanical contactor designed for high-current 12V and 24V DC systems. It is built explicitly to manage battery isolation and power distribution in demanding, harsh-environment applications such as marine vessels, RVs, emergency vehicles, and industrial machinery.
A summary of its key features and product specifications includes:
Key Features
- High-Current Capability: Supports an impressive 500 Amps of continuous current and up to 1,500 Amps of momentary cranking/surge capacity.
- Silver-Alloy Contact Points: Delivers clean, full-voltage switching and far superior conductivity compared to legacy rotary-style battery switches.
- Bullet-Proof Construction: Sealed to IP67 / IP6K9K standards, meaning it is completely dust-tight and waterproof against high-pressure washdowns. It is also ignition-protected, making it safe for installation in gasoline-powered boats and other combustible environments.
- Intuitive Manual Control: Features a high-visibility, bright yellow knob with clear, easy-to-read ON/OFF labels. The knob allows you to manually force the relay open or closed, and can lock it in either position.
- Terminal Stud & Short Protection: Comes with heavy-duty M10 stainless steel studs to handle thick battery cables. It includes a clip-on protective terminal cover with built-in label recesses (including a 40-circuit label sheet) to prevent accidental short circuits.
- Integrated Gore-Tex Vent: Features a built-in moisture-regulating vent that equalizes internal air pressure to prevent condensation build-up behind the seals over long-term field use.
- Modular Expandability: Designed with a compact rectangular footprint that allows it to easily integrate with other Egis XD Series relays, automated charging relays (ACR), or low-voltage disconnects (LVD) using optional link busbars.
