Performance Specifications Designed for 12-48V DC systems, this switch provides simple ON/OFF operation. It supports continuous 275A current at 12V, handles intermittent loads up to 455A, and survives momentary spikes of 1250A. Primary ApplicationSafely severs battery-to-system connections in parked vehicles/watercraft to prevent parasitic drain. Provides reliable power cutoff for automotive, RV, and marine applications during storage or maintenance. Critical Notes Exclusively compatible with 15.5-17mm negative terminals. Never force onto oversized terminals improper sizing risks connection faults. Always switch OFF before motor/battery linkage adjustments. Avoid load-based operations activation under current may permanently damage the switch. Broad CompatibilityCompatible with standard market battery terminals. Functions effectively as a standalone unit or integrated into auxiliary switching circuits. Streamlined InstallationEngineered for plug-and-play functionality, it mounts directly to top-post battery negative terminals without auxiliary wiring or adapters, ensuring instant and secure electrical disconnection. Heavy-Duty Construction Features a flame-retardant ABS housing resistant to arc damage, paired with precision-cast brass connectors for robust durability, optimal conductivity, and extended service life.
