10631700

Overview

The Littelfuse 10631700 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, featuring 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 disconnect capabilities 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 circuitry (SPST or DPST) and ingress protection rating for the intended environment. Cross-reference the datasheet for any ADR compliance needs if operating in regulated regions.

Selection Notes

Select this component based on the need for remote, automated battery disconnection rather than manual operation. Consider the continuous and inrush current ratings required by the specific heavy-vehicle electrical system. Evaluate the necessary ingress protection level and whether time-delay features are needed for the application's operational logic.

Part Context

This component belongs to Littelfuse's Electrical Battery Disconnect Switches series, which provides solenoid-actuated solutions for isolating main battery circuits in demanding environments. These switches serve as critical safety devices in commercial fleets and marine vessels, offering an alternative to manual disconnects by integrating directly into vehicle control systems for enhanced operational safety and convenience.

Replacement Considerations

Consult official Littelfuse substitution guides for confirmed equivalent part numbers. Verify that any replacement maintains identical continuous current ratings, voltage specifications, and circuitry configuration (SPST/DPST). Ensure the substitute meets the same ingress protection standards and physical mounting requirements.
