Home / Product / Relay for Wall-mounted meter / Relay for Dual Circuit / HJE22A-100A Compliant with UC3 Dual Channel Latching RelayProduct Definition: Designed specifically for power equipment requiring multi-circuit switching and high-current control. The product utilizes magnetic latching technology to achieve low-power, high-reliability dual-channel control capabilities, suitable for smart metering, energy management, and multi-load electrical control systems.

Product Advantages:
Dual-Circuit Independent Control: Supports simultaneous or independent switching of two circuits, improving system integration and load management flexibility.
100A High Current Capacity: Can handle high-power loads, meeting the electrical control needs of residential, commercial, and industrial applications.
Magnetic Latching Low-Power Structure: The on/off state is maintained after power failure, significantly reducing energy consumption and heat generation.
UC3 Standard Compliance: Enhanced insulation, withstand voltage, and surge resistance performance, adapting to more stringent power grid environments and safety requirements.
Long-Life Contacts: Contact materials are arc-resistant and wear-resistant, ensuring high stability and a long electrical life.
Low power consumption, low heat generation, and superior overall stability.
Application Areas:
Smart meters and dual-circuit metering equipment
Distributed energy management and load switching systems
Industrial and commercial power control terminals and intelligent power distribution equipment

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.
