HJE33B-120A Compliant with UC3 Three Phase Latching Relay

High Current Carrying Capacity: Each phase supports a high current load of 120A, meeting the stringent switching requirements of high-power three-phase systems.
Extreme Energy Saving: Utilizing magnetic latching technology, power is consumed only during state switching, with zero standby power consumption, significantly reducing system operating energy consumption.
High Reliability Standard: Strictly compliant with the UC3 international standard, ensuring excellent safety and long-term stability under high-voltage environments.
Core Applications: Widely used in key areas such as high-power charging piles, industrial UPS, three-phase smart meters, photovoltaic inverters, and energy storage 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， to prevent the factory from damaging the goods, shoud be strict distinction between the normal product and must not be used.
