Description

This XD heavy-duty battery disconnect combines a manual battery switch and a mechanical contactor in one compact, marine-grade case. Silver alloy contact points support high-amperage, full-voltage switching of up to 500 A continuous, comfortably outperforming legacy rotary battery switches, and the bright yellow knob with a clear on and off label makes the switch state obvious at a glance. Because it is ignition protected it is safe to install in petrol-powered boats and other combustible environments, and the M10 terminal studs accept heavy battery cabling.

The rectangular case is narrower than competing products, so it surface-mounts or rear-panel mounts easily, and the included protective cover with label recesses prevents accidental shorts while keeping circuits identified. Sealed to IP67 and IP6K9K with an integrated Gore-Tex pressure-regulation vent, it shrugs off moisture for reliable long-term operation across a wide -40C to 125C temperature range. It integrates directly with XD Series Flex, ACR and LVD relays using the optional 8790 link and 8791 cross-link busbars.

How does this differ from a traditional rotary battery switch?
It uses silver alloy contact points designed for high-amperage, full-voltage switching, giving greater switching capability than legacy rotary battery switches in a compact, sealed case.
Is it safe to fit in a petrol-powered boat?
Yes. The disconnect is ignition protected, which makes it safe to install in gasoline-powered boats and other combustible environments.
What size cabling do the terminals accept?
The unit uses M10 terminal studs, suitable for the heavy battery cabling typical of high-current disconnect applications.
Can it be combined with XD Series relays?
Yes. It integrates with single, dual and triple XD Flex, ACR and LVD relays using the optional 8790 link and 8791 cross-link busbars.
