Home / Product / Relay for Wall-mounted meter / Relay for Single Phase / HJE11D-100A Compliant with UC2 Single Phase Latching RelayProduct Definition: This product is an innovative, high-efficiency, and energy-saving controller. Its greatest advantage lies in its magnetically latched bistable structure, consuming energy only during operation and maintaining its switching state without requiring power under normal conditions, significantly reducing system energy consumption and heat generation.

Core Values:
Energy Saving and High Efficiency: Switching states is achieved via coil pulse drive, consuming no power during long-term operation, effectively saving energy and reducing temperature rise.
Stable and Reliable: Meets stringent UC2 electrical standards, possessing excellent vibration and shock resistance, and maintaining its state after power failure.
Powerful Load Capacity: With a contact capacity of up to 100A and using arc-resistant silver alloy materials, it can handle frequent switching of single-phase AC loads.
Compact and Durable: Optimized structural design achieves high electrical performance within a limited space, with a mechanical life exceeding 500,000 cycles.
Typical Applications: Widely used in smart meters, photovoltaic power generation systems, energy storage devices, new energy charging piles, and automated control systems requiring long-term energization. Particularly suitable for power management and remote control scenarios requiring low power consumption and high reliability, making it an ideal choice for modern energy-saving power systems.

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, T2, and T3 at the same time on a dual coil, or energize the coil for longer than 1 minute (damage to the coil could occur).
3、Relays have polarity; if the user’s need is different from the 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 a strict distinction between the normal product and it must not be used.
