10820700

Overview

The Littelfuse 10820700 is a manual battery disconnect switch designed for commercial vehicle applications. It operates within 12 V, 24 V, and 48 V DC systems with continuous current ratings ranging from 40 A to 600 A. The device provides a direct, operator-actuated means of isolating the main battery from the electrical system. Available in key-operated, lever-operated, and rotary formats, it supports single-pole and double-pole circuitry configurations. Housings are constructed from various metals or thermoplastics to ensure durability in heavy-duty environments.

Feature Summary

• Provides direct operator-actuated isolation of the main battery from the vehicle electrical system for safety and storage purposes.
• Available in multiple actuator styles including push-button, T-handle, rotary knob, key, and lever to suit different operational needs.
• Housings manufactured from various metals or thermoplastics to withstand heavy-duty marine and commercial application conditions.

Applications

• Primary battery isolation on trucks and buses
• Battery isolation for construction equipment and recreational vehicles
• Anti-theft and safety shutdown mechanisms for fleet vehicles

Procurement Notes

Verify that the selected unit matches the specific voltage rating (12 V, 24 V, or 48 V) and required continuous current capacity for the target commercial vehicle system. Confirm the actuator style and pole configuration align with the installation requirements. Ensure the housing material meets the environmental standards for the intended operating location.

Selection Notes

Select based on the specific DC voltage level and maximum continuous current load of the vehicle's electrical architecture. Choose the appropriate actuator type and enclosure material to match the accessibility and environmental exposure of the installation site. Verify compliance with applicable marine or commercial vehicle battery switch standards.
