10631800

Overview

The Littelfuse 10631800 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 allows operators to isolate the battery without accessing the engine bay. The product is 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
• Compatible with control inputs from cab switches, timers, or battery management systems

Applications

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

Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm compatibility with your vehicle's voltage and current requirements. Ensure the selected variant matches the required ingress protection rating and circuitry configuration (SPST or DPST) for your specific installation environment. Cross-reference with the manufacturer's latest datasheet to confirm availability and any updated regulatory compliance standards such as ADR versions if applicable.

Selection Notes

Select this component based on its ability to handle the specific continuous and inrush current loads of the target heavy-duty electrical system. Consider the need for remote operation versus manual intervention when choosing between electrical and manual disconnect variants. Evaluate the environmental conditions to determine the necessary Ingress Protection (IP) rating, ranging from IP65 to IP69K, ensuring the housing material suits the operational temperature and exposure levels.

Part Context

This component belongs to Littelfuse's Electrical Battery Disconnect Switches portfolio, which focuses on solenoid-actuated solutions for heavy-duty applications. Unlike manual switches, these electrical variants integrate directly into vehicle control systems, offering automated or remote safety features. The series supports various current ratings and circuitry options to meet the diverse demands of buses, trucks, and marine vessels.

Replacement Considerations

Consult official Littelfuse substitution guides for confirmed equivalent part numbers. Verify that any replacement maintains identical continuous current ratings, inrush capabilities, and maximum DC voltage specifications. Ensure the substitute part matches the required circuitry type and physical mounting constraints before implementation.
