10821600

Overview

The Littelfuse 10821600 is a manual battery disconnect switch designed for commercial vehicle applications. It operates at a continuous current rating of 40 A and supports system voltages of 12 V, 24 V, and 48 V DC. The device features a lever-operated actuator style housed in a thermoplastic enclosure. It provides single-pole circuitry for isolating the main battery from the electrical system to ensure safety during maintenance or storage.

Feature Summary

• Provides direct operator-actuated isolation of the main battery from the vehicle electrical system
• Features a lever-operated actuator for manual engagement and disengagement
• Constructed with a thermoplastic housing suitable for heavy-duty commercial environments

Applications

• Commercial truck primary battery isolation
• Bus fleet vehicle safety shutdown
• Construction equipment battery disconnect
• Recreational vehicle anti-theft and storage power cutoff

Procurement Notes

Verify that the specific application voltage (12 V, 24 V, or 48 V) matches the system requirements before procurement. Confirm that the 40 A continuous current rating is sufficient for the intended load isolation needs. Ensure the lever-operated actuator style is compatible with the available installation space and user interface requirements for the target vehicle or equipment model.

Selection Notes

Select this component when a manual, operator-actuated disconnect is required for safety or storage purposes in light-duty commercial applications. The 40 A rating limits its use to lower current circuits compared to higher-amperage series options. Consider the thermoplastic housing material if weight reduction is prioritized over metal housings found in heavier marine or industrial duty cycles.

Part Context

This part belongs to the Littelfuse manual battery disconnect switch portfolio, which includes key-operated, lever-operated, and rotary formats. These switches are engineered to meet applicable standards for marine and commercial vehicle battery switch applications, offering both single-pole and double-pole configurations across various current ratings up to 600 A.

Replacement Considerations

Consult official Littelfuse documentation for confirmed substitute part numbers within the same series or equivalent current/voltage rated models. Verify compatibility with existing mounting hardware and actuator access points when considering alternative components.
