HJE31A-80A Compliant with UC2 Vertical Type Single Phase Latching Relay

This product utilizes magnetic latching bistable technology, making it an energy-saving power control component. It consumes energy only momentarily when the coil is pulse-driven; once the state switch is complete, it maintains the current on/off position without continuous power supply, reducing energy consumption and operating temperature rise at the source.

Product Highlights:

Energy-Saving Silent Operation: Pulse-driven mechanism maintains "zero" power consumption over long periods, significantly improving system energy efficiency.

Power-Off Memory Retention: Possesses self-holding capability, maintaining the original on/off state even after an unexpected power outage, enhancing system stability.

High Current Reliable Load Capacity: 100A load capacity combined with arc-resistant contact materials, suitable for high-load, frequent switching in single-phase AC environments.

Compact, Long-Life Design: Compact and reliable structure with mechanical durability exceeding 500,000 cycles, adaptable to various industrial environments.

Main Application Areas:
Suitable for remote on/off control of smart meters, circuit management of photovoltaic energy storage systems, power modules for charging piles, and automated equipment requiring long-term low-power standby. This product is particularly suitable for power control systems with high energy-saving requirements and power-off state memory functions, providing reliable protection for green and efficient electrical architectures.

Application Notes

1、All relays are shipped in the “closed” position. It is possible that during transit or final assembly,y 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 different from information,shoud be 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.
