Perko Medium Duty Battery Disconnect Shut Off/On - 250 Amp Continuous, 12-32VDC

The Perko Medium Duty Battery Disconnect Shut Off/On is the marine electrical system's most critical safety and maintenance component for anglers and boaters who demand reliability. After years on the water, any experienced captain knows that a failed battery switch can strand you offshore or compromise your vessel during an emergency. This ignition-protected disconnect switch isolates your boat's entire electrical system in seconds—whether you're shutting down for storage, performing maintenance, or responding to an electrical fault. Built for 12, 24, and 32-volt marine systems, it handles the demanding electrical loads of modern fishing boats, cruisers, and commercial vessels.

Engineered for continuous duty, the Perko 9601DP switch delivers 250 amps continuous capacity with peak intermittent ratings of 360 amps—sufficient for twin-engine boats with high-demand electronics suites including GPS, sonar, autopilots, and thruster systems. The ignition protection design prevents dangerous arcs when switching under electrical load, a critical safety feature when disconnecting from energized systems. Its compact footprint (7 x 3 x 8 inches) and lightweight construction (0.8 lbs) make it easy to mount in engine compartments, battery boxes, or electrical panels without consuming valuable space. The switch mechanism is sealed against salt spray and moisture infiltration, materials and design priorities that reflect decades of Perko's marine manufacturing expertise.

Professional anglers, charter operators, and cruising boaters rely on this disconnect switch as the first line of defense against battery drain during layups and as an emergency kill switch during electrical emergencies. Installation works with both unitized and non-unitized alternators, providing compatibility across virtually all marine electrical architectures. Whether you're winterizing a saltwater fishing platform or upgrading an aging electrical system, this Perko medium-duty switch delivers the dependability that keeps you operational. Mounting hardware and wiring connections follow standard marine best practices, making integration straightforward for both DIY installers and professional marine technicians.
