Home / Product / Relay for Overvoltage and Undervoltage Protector / Relay for Undervoltage / HJE11C-90A-250VAC Latching RelayProduct Overview: In today's increasingly complex power system voltage fluctuations, the HJE11C-90A-250VAC magnetic latching relay has been developed, specifically optimized for voltage anomaly protection scenarios. As a core component of the over/under voltage protector series, it not only quickly disconnects the circuit when the voltage exceeds the safe threshold, but also ensures continuous and stable protection status through magnetic latching technology, building an intelligent safety barrier for your electrical equipment.

Core Protections:
Precise Voltage Protection: Rapid response to over/under voltage anomalies; 90A high current capacity ensures reliable disconnection.
Zero Power Consumption Safety Lockout: The magnetic latching structure achieves self-maintained protection status, ensuring protection even during power outages.
Industrial-Grade Durable Design: 250VAC withstand voltage rating, adaptable to long-term operation in complex power grid environments.
Key Scenarios Protected:
Over/Under Voltage Protection for Residential and Commercial Distribution Boxes
Power Grid Voltage Anomaly Protection for Photovoltaic Inverters
Power Supply Voltage Safety Assurance for Precision Instruments and Equipment
Voltage Fluctuation Protection for Industrial Production Equipment

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.
