10836062

Overview

The Littelfuse 10836062 is a manual battery disconnect switch designed for commercial vehicle and marine applications. It operates as a single-pole, double-throw (SPDT) circuit breaker with a continuous current rating of 400 A at 12 V DC systems. The device features a lever-operated actuator style and is housed in a thermoplastic enclosure rated for IP67 ingress protection, ensuring water resistance in harsh environments. This component provides a direct, operator-actuated means of isolating the main battery from the electrical system for safety, storage, and anti-theft purposes.

Feature Summary

• Provides operator-actuated isolation of the main battery from the vehicle electrical system for enhanced safety and security.
• Features a robust lever-operated actuator mechanism for reliable manual engagement and disengagement.
• Constructed with a thermoplastic housing that meets IP67 standards for water-resistant performance in heavy-duty marine and commercial settings.

Applications

• Primary battery isolation for trucks and buses
• Marine vessel electrical system shutdown
• Construction equipment maintenance safety
• Recreational vehicle power management

Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm the exact voltage rating, current capacity, and actuator style required for your application. Ensure compatibility with existing mounting hardware and wiring terminals. Confirm that the IP67 rating meets the environmental exposure requirements of the installation site. Cross-reference with updated datasheets to ensure no design changes have occurred since the last procurement cycle.

Selection Notes

Select this model when a high-current, manually operated disconnect is required for 12 V DC systems. The SPDT configuration allows for versatile circuit control compared to standard SPST switches. Consider the IP67 rating if the installation location is exposed to water or dust. The lever actuator offers distinct tactile feedback compared to rotary or key-operated alternatives, which may be preferred for frequent operational access.

Part Context

This component belongs to Littelfuse's portfolio of manual battery disconnect switches, which are engineered for safety and reliability in demanding environments. These switches are commonly used in commercial vehicles, marine craft, and industrial equipment to prevent parasitic drain and protect against short circuits. The series includes various ratings and actuator styles to suit different operational needs and regulatory standards.

Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalent part numbers. Ensure any replacement matches the original continuous current rating, voltage class, and physical mounting dimensions. Verify that the new unit maintains the same ingress protection rating and actuator type to preserve operational consistency and safety compliance.
