SHACMAN High-Current 500A Battery Kill Switch Auxiliary Terminal Memory Saver for ISUZU SHACMAN FTR FVR Truck 24V DC

High-Current 500A Battery Kill Switch with Auxiliary Terminal

This advanced 500A battery kill switch features a dedicated auxiliary terminal circuit that maintains low-current power to vehicle electronics (ECU, radio memory, clock) while disconnecting the main high-current circuit. Designed for ISUZU FTR, FVR and SHACMAN medium to heavy-duty trucks operating on 24V DC systems, this switch eliminates the inconvenience of resetting vehicle electronics after each battery disconnect.

Key Features

• Auxiliary Memory Circuit: Dedicated fused 5A auxiliary terminal maintains continuous power to ECU memory, radio presets, GPS trackers, and clock settings when the main circuit is disconnected
• 500A Main Circuit Rating: High-current main path handles all heavy electrical loads including starter motor, alternator, and main power distribution with 2000A surge capacity
• Solid Copper M12 Studs: Main terminals use solid copper M12 studs for maximum current transfer with minimal resistance, tin-plated for corrosion protection
• Independent Circuit Isolation: Main and auxiliary circuits are electrically isolated, preventing backfeed from auxiliary loads into the main disconnect path
• Manual Override Lever: Ergonomic high-visibility red lever for quick manual disconnect in emergency situations, operable with gloved hands
• Heavy-Duty Steel Base Plate: Reinforced mounting plate with vibration-dampening rubber grommets for secure chassis or frame rail installation
• Visual Status Indicator: Integrated LED status indicator confirms ON/OFF state visible from a distance, powered by the auxiliary circuit
