In multi-user centralized power supply systems, safe and stable load control is crucial for ensuring fair and safe electricity use. The HJE31A relay is specifically designed for multi-user electricity meters, offering a high 60A load capacity and compact structure, providing efficient and reliable circuit control solutions for apartment buildings, commercial clusters, industrial parks, and other scenarios.

Core Advantages:
Precise Branch Control: Adapts to independent metering of multiple circuits, enabling intelligent on/off control and management of different user loads.
Strong and Safe Load Capacity: Silver alloy contacts combined with optimized heat dissipation design ensure long-term stable switching and reliable overload protection.
Compact and Efficient Integration: Vertical installation design saves internal space and is compatible with high-density integrated metering equipment.
Quiet and Long-Life Operation: Low operating noise and a mechanical lifespan exceeding 200,000 cycles meet long-term maintenance-free requirements.
Typical Application Scenarios:
Residential communities with multi-household centralized electricity meters
Commercial street shops with individual metering systems
Industrial park leased factory buildings with intelligent power distribution
Smart charging pile multi-channel control module
