Home / Product / Relay for DIN rail meter / Three-phase DIN rail mounted relay / HJE32A-100A Integrated Latching Relay with Shunt/CT for 7P DIN Rail MeterProduct Definition: The HJE32A-100A is an innovative integrated three-phase relay designed specifically for 7P DIN rail meters. It aims to perfectly integrate three-phase metering and control, significantly simplifying system design.

High Integration, Space-Saving Advantage: By integrating the functions of three independent relays into one unit, its size is reduced by over 50%! This frees up valuable space in your 7P DIN rail meter design, enabling a higher density of functional layouts.
Powerful Performance, Consistent Stability: With a 100A high current carrying capacity, it easily handles industrial-grade three-phase loads, ensuring absolute reliability and accurate metering of power supply to equipment.
Core Application Scenarios: Specifically designed for centralized three-phase power metering and control scenarios such as industrial production lines, large commercial complexes, and data centers, it is the core choice for building efficient and compact three-phase intelligent metering 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 good,s shoud be strict distinction should be made between the normal product and those that must not be used.
