10843300

Overview

The Littelfuse model 10843300 is an electrical battery disconnect switch designed for commercial vehicle applications. It enables remote, solenoid-actuated disconnection of the main battery circuit. The device supports control via cab-mounted switches, timer relays, or battery management systems. It is rated for high continuous current and inrush current requirements typical of heavy-vehicle electrical systems. The switch provides fast disconnect times to protect against fire and electrical damage following accidents or faults. This component allows operators to isolate the battery without accessing the engine bay.

Feature Summary

• Enables remote isolation of the main battery circuit through solenoid actuation
• Provides rapid disconnection to mitigate fire and electrical damage risks during faults
• Compatible with external control inputs such as timer relays and battery management systems

Applications

• Commercial buses
• Marine applications
• Industrial equipment

Procurement Notes

Verify that the specific part number matches the required continuous and inrush current ratings for the target vehicle system. Confirm ingress protection class suitability for the installation environment. Ensure compatibility with existing control logic, whether utilizing simple cab switches or programmable battery management systems. Cross-reference mechanical mounting dimensions against chassis specifications prior to ordering.

Selection Notes

Select this component when remote battery isolation is required for safety or maintenance purposes in heavy-duty environments. Consider the available circuitry options, including single-pole or double-pole configurations, based on system architecture. Evaluate versions with time delay features if sequential power-down sequences are necessary. Verify ADR compliance requirements for road transport applications before finalizing the selection.

Part Context

This product belongs to the Littelfuse electrical battery disconnect switch portfolio for commercial vehicles. These switches serve as critical safety components by allowing operator-initiated power removal. They replace manual disconnect mechanisms, offering enhanced convenience and safety by eliminating the need for physical access to battery compartments during emergency or routine isolation procedures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing legacy units, verify that the new switch meets or exceeds the original continuous current rating and voltage specifications. Ensure the replacement maintains compatible control signal interfaces and physical mounting constraints.
