FH29LA 120A Latching Relay CQC Compliant

• Smart Electricity Meter

FH29LA Electric Latching Relay 120A Switching Capability is a high-performance electromagnetic latching relay designed for applications requiring high switching capability. It is rated for 120A load and can support voltages up to 250VAC, making it suitable for industrial, construction, and commercial use. The relay adopts magnetic holding technology and is triggered by a pulse signal. It can maintain the current state after a power failure, thereby realizing a passive holding function, which gives it significant advantages in remote control, automation systems, and energy management. FH29LA provides two configuration options: single coil and double coil. Users can choose the appropriate version according to their needs. Its contact form is single-pole double-throw (SPDT), which can meet various circuit switching requirements. The contact material of the relay is silver-tin oxide alloy (AgSnO2), which has low contact resistance and high durability, ensuring long-term stable operation. The product is compact, measuring only 54*110*22mm and weighing about 380g, making it very suitable for application scenarios with limited space. In addition, FH29LA adopts a low-power design with almost no power consumption between switching states, further improving energy efficiency. Its mechanical life can reach 100,000 times, and its electrical life exceeds 10,000 times, making it suitable for environments with frequent operations. FH29LA also supports customization services, allowing users to adjust relay parameters such as coil voltage, contact configuration, etc., according to specific needs. This flexibility enables it to be widely used in smart meters, solar controllers, and industrial automation equipment. FH29LA is an electromagnetic latching relay that combines high performance, high reliability, and flexibility. With its excellent switching capability and low power consumption, it is an ideal choice for various complex electrical systems.
