The HJE12A-120A is a high-performance magnetic latching relay designed for power control systems requiring long-term stable operation and extreme energy efficiency.

Key Highlights: Zero Power Consumption, Green Pioneer: Utilizing advanced magnetic latching technology, the coil consumes power only during the moment of activation, resulting in zero power consumption when holding the state! This significantly reduces standby power consumption for your devices, making it the top choice for green energy-saving designs.
Powerful Switching, Worry-Free Safety: With a 120A high current rating and 250VAC high voltage withstand capability, it easily handles industrial-grade load surges, ensuring clean and decisive switching every time, providing unparalleled circuit protection.
Application Scenarios: Ideal for smart meters, prepaid controllers, solar inverters, and uninterruptible power supplies (UPS)—systems requiring long-term state maintenance and strict energy consumption control!
