10824100

Overview

The Littelfuse 10824100 is a manual battery disconnect switch from the Commercial Vehicle Products series, designed for isolating main batteries in heavy-duty applications. It operates at 24 V DC with a continuous current rating of 300 A. The device features a single-pole single-throw (SPST) circuit configuration and is housed in a waterproof enclosure meeting IP67 ingress protection standards. This construction ensures reliable performance in harsh commercial vehicle environments.

Feature Summary

• Provides direct operator-actuated isolation of the main battery from the electrical system for safety and storage purposes.
• Waterproof housing design meets IP67 ingress protection standards for durability in harsh conditions.
• Available in key-operated actuator formats to secure battery disconnection against unauthorized access.

Applications

• Primary battery isolation for trucks and buses
• Anti-theft security systems for fleet vehicles
• Safety shutdown during maintenance or repair procedures

Procurement Notes

Verify that the required voltage rating matches the 24 V DC system specification. Confirm the continuous current requirement does not exceed 300 A. Ensure the installation environment necessitates the IP67 waterproof rating. Check that the key-operated actuator style aligns with existing security protocols. Validate compatibility with the specific chassis mounting requirements before procurement.

Selection Notes

Select this model when a robust, waterproof disconnect solution is required for 24 V commercial vehicle systems. The 300 A rating suits high-current applications typical in heavy-duty transport. The IP67 rating is essential for exposed mounting locations. Consider the key-operated feature if anti-tamper security is a priority over lever or rotary alternatives.

Part Context

This component belongs to the Littelfuse manual battery disconnect switch portfolio, which includes options for 12 V, 24 V, and 48 V systems. The series offers various actuator styles and circuitry configurations to meet diverse commercial vehicle and marine isolation needs. It serves as a critical safety interface between the power source and the vehicle load.

Replacement Considerations

Ensure any substitute part maintains the 24 V DC rating and 300 A continuous current capacity. Verify that the replacement also meets IP67 waterproof standards. Confirm the SPST circuitry and key-operated actuator type are compatible with the existing panel cutout and locking mechanism.

FAQ

What is the ingress protection rating of the 10824100?

The 10824100 has an IP67 rating, indicating it is dust-tight and protected against immersion in water up to 1 meter for 30 minutes.

Is this switch suitable for 12 V systems?

While rated for 24 V DC, the 300 A continuous current rating makes it electrically capable of handling 12 V systems, though it is specifically categorized under the 24 V series.
