10842200

Overview

The Littelfuse 10842200 is a manual battery disconnect switch designed for commercial vehicle and marine applications. It operates on a 24 V DC system with a continuous current rating of 300 A. The device features a single-pole, single-throw (SPST) circuitry configuration. It is housed in a waterproof enclosure that meets Ingress Protection standards up to IP67 and IPX9K, ensuring durability in harsh environments. This switch 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 direct operator-actuated isolation of the main battery from the vehicle or equipment electrical system
• Waterproof housing design ensures reliable performance in harsh commercial vehicle and marine environments
• Single-pole, single-throw circuitry configuration for straightforward power cutoff functionality

Applications

• Commercial vehicles requiring primary battery isolation for maintenance safety
• Marine vessels needing waterproof battery disconnect solutions
• Fleet vehicles and construction equipment for anti-theft and storage protection

Procurement Notes

Verify that the required voltage rating matches your system's 24 V DC specification and confirm the continuous current load does not exceed 300 A. Ensure the installation environment requires the specified IP67/IPX9K waterproof rating. Check that the single-pole configuration aligns with your circuit design needs before procurement.

Selection Notes

Select this component when a robust, waterproof manual disconnect is needed for 24 V systems carrying up to 300 A. Consider the SPST configuration for simple on-off control. Evaluate environmental exposure to determine if the high ingress protection level is necessary compared to lower-rated alternatives.
