HD系列300 A重型大电流自锁继电器是远程操作的双稳态继电器断路器，专为大电流电路和需要高性能的应用而设计，例如大逆变器负载和高环境温度情况。这些重型汽车继电器的密封等级为IP67/IP69K，可耐受灰尘、水和恶劣天气，以及高冲击和振动的环境。
HD系列双稳态继电器无需将沉重的铜电缆布线到位置更方便的机械断路器，因此在成本和重量方面具有显著优势。相反，电缆可以直接布线到负载，HD系列继电器位于靠近电池的位置或与所需的电缆布线保持一致。然后，HD锁存继电器的远程控制可以放置在车辆上任何方便的位置，并采用细线束将HD继电器连接到控制开关。
- Supports high-current continuous loads up to 300 A and intermittent loads up to 1500 A for 10 seconds
- Available with a 12 VDC coil or 24 VDC coil
- Low power consumption: Magnetically latched or electronically controlled bistable operation draws no current in the on or off position
- Remote operation eliminates long runs of heavy cable, minimizing cable complexity, cost, and vehicle weight
- Sealed to an IP67/IP69K rating for protection against dust, debris, and water ingress
- Silver alloy contacts assure the lowest voltage drop/resistance and extend cycling life
