Littelfuse HD Series Chassis Automotive Relay, 12V Coil Voltage, 300A Continuous Current, SPDT M 880086

The Littelfuse 880086 HD Series Chassis Automotive Relay is engineered for high amperage vehicle circuits with a 12V coil voltage and a single pole double throw (SPDT M) contact configuration. This bi-stable (latched) relay provides an extremely efficient switching solution by drawing no current in the On or Off positions, thereby eliminating continuous battery demand.

Its robust chassis mount design combined with a silver alloy and copper contact material ensures high durability and reliable performance in industrial and automotive environments. The relay is sealed to IP67, which allows installation outside the vehicle cab while maintaining resistance to dust and water ingress. It utilizes the industry standard Deutsch DT06-6S connector to facilitate secure wiring connections.

Rated for a continuous current of 300 A and an inrush current of 1500 A for 10 seconds, this relay is suitable for heavy vehicles, construction machinery, agricultural equipment, military vehicles, and mining operations. Operating reliably within a temperature range of -50°C to +105°C, it withstands harsh conditions, supported by its robust shock resistance of 10 G and vibration resistance of 8 G.

The relay enhances system efficiency by reducing the need for heavy copper cabling traditionally routed from the battery to auxiliary loads. The HD Series provides an effective remote switching solution with the switch purchased separately. This relay is ideally suited for demanding industrial applications requiring high current load switching and robust environmental protection.

Supports continuous current up to 300 A with a 1500 A inrush capacity for 10 seconds. Bi-stable relay design eliminates continuous power draw in On/Off positions. Sealed to IP67 for operation in harsh environmental conditions.

Shock resistance of 10 G and vibration resistance of 8 G for rugged applications. Operates reliably across a wide temperature range from -50°C to +105°C. Chassis mount type for stable and secure coupling. Constructed with silver alloy and copper contact material for enhanced conductivity and durability.

Industry standard Deutsch DT06-6S connector for reliable wiring. Manufactured in Mexico, meeting international quality standards.

This Littelfuse automotive relay offers a high-quality and efficient solution for industries including heavy vehicles, construction, agriculture, military, and mining. It reduces unnecessary power losses and cabling complexity, making it an essential component in demanding relay applications.
