HJE33C-120A Compliant with UC3 Large Current Three Phase Latching Relay

Core Advantages:

Extreme Energy Efficiency: Pulse drive and state self-locking reduce system operating energy consumption and temperature rise at the source.

Safety First: Meets stringent UC3 electrical standards." Enhanced insulation and arc resistance provide a higher level of protection for personnel and equipment.

Powerful performance: Single-circuit contact switching capacity up to 120A easily handles the frequent start-stop of three-phase inductive loads such as motors and transformers.

Stable and durable: Optimized for industrial environments, it is vibration and shock resistant, ensuring long-term stable operation under harsh conditions.

Enabling key scenarios:

Intelligent control systems for industrial three-phase motors

Power modules for photovoltaic inverters and energy storage power stations

New energy charging piles and high-power battery swapping equipment

Power management for heavy equipment in automated production lines

Application 

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 good,s shoud be strict distinction should be made between the normal product and those that must not be used.
