10843600

Overview

The Littelfuse 10843600 is a manual battery disconnect switch designed for commercial vehicle and marine applications. It provides a direct, operator-actuated means to isolate the main battery from the electrical system for safety, storage, or anti-theft purposes. The device is rated for 24 V DC systems with a continuous current rating of 300 A. It features a water-resistant housing that meets Ingress Protection (IP) standards, ensuring reliability in harsh environments. This single-pole switch allows mechanics to safely shut down power during maintenance and prevents parasitic loads from draining the battery during storage.

Feature Summary

• Provides direct operator-actuated isolation of the main battery from the vehicle electrical system
• Features a water-resistant housing designed for heavy-duty marine and commercial applications
• Enables safe shutdown of electrical systems for maintenance and prevents parasitic drain during storage

Applications

• Commercial trucks and buses
• Marine vessels
• Construction equipment
• Recreational vehicles

Procurement Notes

Verify the specific actuator style and mounting configuration required for your chassis panel before ordering. Confirm that the 24 V DC voltage rating and 300 A continuous current capacity align with your system's maximum load requirements. Ensure the IP rating of the selected variant meets the environmental exposure conditions of the installation site. Cross-reference the part number with official Littelfuse documentation to confirm availability and compliance with applicable marine or commercial vehicle standards.

Selection Notes

Select this component when a robust, manual master cutoff is needed for high-current 24 V systems. Consider the available actuator styles, such as key-operated or lever-operated, based on security and accessibility needs. Evaluate the housing material options, including metals or thermoplastics, to match corrosion resistance requirements. Ensure the switch fits the designated panel cutout dimensions and wiring terminal specifications for seamless integration into existing electrical architectures.
