Home / Product / Relay for Wall-mounted meter / Relay for Dual Circuit / HJE24A-100A Compliant with UC3 Dual Channel Large Current Latching RelayProduct Definition: This product is a dual-channel high-power magnetic latching relay conforming to the stringent UC3 standard, designed specifically for high-safety, high-efficiency energy control scenarios. It integrates dual independent high-current channels with magnetic latching technology, allowing for complete power-off operation after state switching, while simultaneously meeting the dual requirements of system energy saving and multi-circuit management.

Core Values:
Dual 100A independent control capability allows for synchronous or time-sharing management of two high-power loads, providing greater system configuration flexibility.
Compliant with UC3 enhanced electrical standards, offering higher levels of insulation performance and safety margins, suitable for more demanding operating environments.
Magnetic latching structure achieves zero static power consumption after switching, significantly reducing overall system energy consumption and heat accumulation.
Compact and robust structure, vibration-resistant and shock-resistant, ensuring long-term stable operation in complex industrial environments.
Main Applications:
Particularly suitable for commercial and industrial energy storage systems, high-power photovoltaic inverters, dual-gun high-power charging piles, power distribution automation, and industrial control cabinets requiring high safety redundancy. This product is an ideal choice for demanding, high-power dual-loop control applications that balance performance, safety, and energy efficiency.

Application Notes
1、All relays are shipped in the “closed” position. It is possible that during transit or final assembly, the relay could change its state to the “open” position. Therefore, it is recommended that all relays be set to the desired state of the relay via a power supply.
2、In order to maintain an “open” or “closed” state of the relay, the coil voltage should reach the rated voltage. The pulse width should be 5 times the operating time to ensure a proper change of state. Do not energize both T1, T,2 and T3 at the same time on a dual coil, or energize the coil for longer than 1 minute (damage to the coil could incur).
3、Relays have polarity; if the user’s need is different fromthe information, please contact us.
4、The relay to the factory inspection and use should be handled to prevent damage to the factory for damaging the goods, shoud be strict distinction between the normal product and must not be used.
