Din Rail Dual Display Over/Under Voltage & Current Protector
Din Rail Dual Display Over/Under Voltage & Current Protector
HpLive Din Rail Dual Display Voltage & Current Protector
Keep your home appliances and commercial circuits safe with the HpLive Din Rail Dual Display Voltage & Current Protector. This fully adjustable, auto-reconnecting protective device offers triple-layer circuit defense — monitoring overvoltage, undervoltage, and overcurrent conditions in real time, all from a large, easy-to-read digital display.
Made in Mainland China.
Key Features
- Triple Protection with Auto-Reconnect: Instantly shuts down during overvoltage, undervoltage, or overload events. Once the line returns to normal parameters, the device automatically reconnects power — no manual reset required.
- Fully Adjustable Protection Ranges: Customize settings to your exact needs. Overvoltage adjustable from AC 230V–300V, undervoltage from AC 140V–210V, and overcurrent from 1–40A / 63A / 80A / 100A (model dependent). Ideal for tailoring protection to different rooms or load requirements.
- Large Dual Digital Display: Real-time working voltage and current readings shown on a clear, large-screen digital display — so you always know exactly what your circuit is doing at a glance.
- Smart Tiered Overload Protection: Set the continuous overload trip count from 1 to 20 times (default off). For example, set to 2 and the unit will auto-recover after the first overload event but trigger a permanent shutdown on the second consecutive overload — delivering intelligent, tiered circuit defense.
- High Accuracy & Reliable Build: Premium-grade chips deliver stable operation with ±1% measurement accuracy. Suitable for home distribution panels, commercial circuits, dormitories, and more.

Frequently Asked Questions
Q: What types of circuits is this din rail voltage protector compatible with?
A: This din rail voltage & current protector is designed for standard AC circuits operating between 140V and 300V. It is suitable for home distribution panels, commercial electrical circuits, dormitories, and any single-phase AC load installation where overvoltage, undervoltage, or overcurrent protection is required.
Q: Does this voltage protector require manual resetting after a trip event?
A: No. The device features an automatic reconnect function. Once the line voltage or current returns within the pre-set safe operating range and the recovery delay period has elapsed, the protector will automatically restore power — no manual intervention needed. However, if the overload trip count limit is reached, a permanent shutdown is triggered until manually reset.
Q: Can I adjust the overvoltage and overcurrent thresholds to suit my specific needs?
A: Yes. The protection thresholds are fully adjustable. Overvoltage can be set between 230V and 300V, undervoltage between 140V and 210V, and overcurrent between 0.5A and up to 40A, 63A, or 80A depending on the model selected. This makes it easy to tailor the device to different rooms, appliances, or load requirements.
Q: What is the measurement accuracy of this dual display protector?
A: The HpLive voltage & current protector uses premium-grade chips that deliver ±1% measurement accuracy, ensuring that the real-time voltage and current readings on the digital display are highly reliable for circuit monitoring.
