10843362

Overview

The Littelfuse 10843362 is an electrical battery disconnect switch designed for commercial vehicles, marine applications, and industrial equipment. It enables remote, solenoid-actuated disconnection of the main battery circuit, controlled by a cab-mounted switch, timer relay, or battery management system. This device isolates the battery without requiring access to the engine bay or battery compartment. Rated for high continuous current and inrush current requirements typical of heavy-vehicle electrical systems, it features fast disconnect times to protect against fire and electrical damage following accidents or faults.

Feature Summary

• Enables remote isolation of the main battery circuit via solenoid actuation
• Provides rapid disconnection to mitigate fire and electrical damage risks
• Operates independently of manual engine bay access

Applications

• Commercial vehicle battery isolation
• Marine application power cutoff
• Industrial equipment safety shutdown

Procurement Notes

Verify that the specific part number corresponds to the required continuous and inrush current ratings for your heavy-duty application. Confirm compatibility with the intended control method, such as cab switches or battery management systems. Ensure the ingress protection rating meets environmental requirements. Cross-reference official Littelfuse documentation to confirm circuitry type and voltage specifications before procurement.

Selection Notes

Select this component based on its ability to handle high continuous and inrush currents characteristic of heavy-vehicle systems. Consider the need for remote operation versus manual intervention. Evaluate the required ingress protection level for the installation environment. Ensure the switching speed aligns with safety protocols for accident or fault scenarios.

Part Context

This product belongs to the Littelfuse electrical battery disconnect switch portfolio, which serves commercial vehicles, marine, and industrial sectors. These switches provide remote control capabilities unlike manual variants. The series is engineered for durability in demanding environments, offering various circuitry options and protection ratings to suit different heavy-duty electrical system architectures.

Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalent part numbers. Ensure any replacement maintains identical continuous current, inrush current, and voltage ratings. Verify that the alternative unit supports the same remote control interface and ingress protection standards.
