10826200

Overview

The Littelfuse/Commercial Vehicle Products part number 10826200 is a manual battery disconnect switch designed for commercial vehicle applications. It provides a direct, operator-actuated means of isolating the main battery from the vehicle electrical system to ensure safety during maintenance, prevent parasitic drain during storage, and mitigate anti-theft risks. This component serves as a primary isolation point within heavy-duty DC power distribution architectures.

Feature Summary

• Provides direct operator-actuated isolation of the main battery from the vehicle electrical system
• Designed to prevent further damage or injury in the event of short circuit fires by allowing rapid deactivation
• Enables mechanics to ensure complete shutdown of the vehicle's electrical system for safe servicing

Applications

• Primary battery isolation for trucks and buses
• Safety shutdown for construction equipment such as backhoes and bulldozers
• Parasitic load prevention for stored recreational vehicles and fleet vehicles

Procurement Notes

Verify that the specific actuator style and mounting configuration match the original equipment requirements. Confirm ingress protection ratings align with the installation environment. Ensure voltage and current ratings exceed the maximum system parameters to guarantee reliable operation under all load conditions.

Selection Notes

Select this component based on its role as a master disconnect rather than a standard fuse. Consider the required actuator type, such as key-operated or lever-operated, depending on security needs. Evaluate housing material compatibility with marine or commercial environments to ensure durability against corrosion and physical impact.

Part Context

This part belongs to the Littelfuse Commercial Vehicle Products portfolio, which focuses on protecting, controlling, and distributing electrical power for OEM and aftermarket solutions. The product line includes fuses, relays, and switches engineered for harsh environments typical of heavy-duty transportation and industrial machinery sectors.

Replacement Considerations

Ensure any substitute maintains equivalent continuous current rating and voltage specifications. Verify mechanical fitment including stud size and terminal configuration. Confirm that the replacement meets the same Ingress Protection standards required for the specific application environment.
