Home / Product / Relay for DIN rail meter / Three-phase DIN rail mounted relay / HJE34A-80A Integrated Latching Relay with CT for 4P DIN Rail MeterA Revolution in Integrated Three-Phase Power Control
This is a highly integrated 4-pole three-phase rail relay, designed specifically for intelligent control and power distribution protection of three-phase loads. It integrates three-phase circuit on/off, status indication, and rail mounting, redefining compact three-phase control solutions.

Why Choose It?
Integrated Three-Phase Control: A single device enables synchronous on/off of three-phase lines, simplifying wiring and saving space.
Compact Rail Mounting: The integrated structure adapts to standard rails, significantly reducing cabinet space and installation time.
Safe Full-Pole Disconnection: The 4-pole fully isolated design ensures complete disconnection of all three phases, enhancing safety.
80A High-Load Capacity: High-quality contact materials support stable load bearing, capable of handling inductive loads such as motors and pumps.
Typical Applications:
Small Three-Phase Motor Control Cabinet
Commercial and Industrial Three-Phase Equipment Distribution Box
Photovoltaic Three-Phase Micro-Inverter Output Terminal
Charging Pile Three-Phase Power Management Module

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, 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, there should be a strict distinction between the normal product and those that must not be used.
