Sea-Dog Line 830401-1 SD-53 40 Amp Battery Disconnect Switch with Circuit Breaker

The Sea-Dog Line SD-53 Battery Disconnect (830401-1) is a compact 40-amp battery disconnect switch with integrated circuit breaker, purpose-built for marine and powersports electrical systems. Its small footprint makes it an excellent choice for installations in tight or confined spaces where a traditional separate switch and breaker combination simply won't fit.

By combining a rotary disconnect switch and a resettable circuit breaker into a single unit, the SD-53 eliminates the need for additional components and reduces both material cost and installation labor. When the breaker trips, it can be manually reset without replacing any fuses, keeping your vessel or vehicle operational with minimal downtime.

Key Features:

• 40-amp rating — suitable for protecting marine electrical circuits and battery connections
• Integrated circuit breaker — resettable breaker and disconnect switch combined in one unit
• Compact, low-profile design — ideal for close-quarters installation in marine, RV, and powersports applications
• Rotary switch operation — simple on/off disconnect for safe battery isolation
• Marine-grade construction — designed to withstand the harsh moisture and vibration conditions of on-water use
• Easy panel mounting — straightforward installation into an electrical panel or enclosure

The Sea-Dog Line 830401-1 SD-53 is a reliable solution for anyone needing a space-saving battery disconnect with built-in overcurrent protection for boats, personal watercraft, RVs, or other powersports vehicles.
