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 Protective Device
Keep your home appliances, commercial circuits, and distribution panels safe with the HpLive Din Rail Dual Display Voltage Protector. This fully adjustable, self-resetting protective device monitors real-time voltage and current, automatically disconnecting power during overvoltage, undervoltage, or overload events — and reconnecting once conditions return to normal. Made in Mainland China.
Key Features
- Triple Protection with Auto-Reconnect: Instantly disconnects during overvoltage, undervoltage, or overload faults. Automatically restores power when the line returns to normal — no manual reset required.
- Fully Adjustable Protection Ranges: Overvoltage adjustable from AC 230V–300V, undervoltage from AC 140V–210V, and overcurrent from 0.5A up to 40A, 63A, or 80A depending on model — perfect for tailoring protection to different rooms or load requirements.
- Large Dual Digital Display: Clear, large-screen display shows real-time working voltage and current simultaneously so you can monitor circuit status at a glance.
- Smart Tiered Overload Protection: Set continuous overload trip count from 1 to 20 times (default off). For example, if set to 2, the unit auto-recovers after the first overload but permanently disconnects on the second consecutive overload — giving you smarter, tiered defense.
- Premium-Grade Chips: Built with high-quality chips for stable operation and ±1% measurement accuracy, suitable for home distribution panels, commercial circuits, and dormitories.
- Easy Din Rail Mounting: Standard 35mm Din Rail compatible; compact size (38mm × 68mm × 86mm) fits neatly inside most electrical enclosures.

Frequently Asked Questions
Q: What types of circuits is this din rail voltage protector compatible with?
A: This din rail dual display protector is compatible with AC 140–300V circuits, making it suitable for home distribution panels, commercial electrical circuits, and dormitory setups. It mounts on a standard 35mm Din Rail and works with a wide range of load requirements.
Q: Does the voltage protector reset automatically after tripping?
A: Yes. Once the line voltage or current returns within the safe operating range, the device automatically reconnects power after the programmed recovery delay (default 30 seconds). No manual reset is needed for standard fault events.
Q: Can I adjust the overvoltage and undervoltage trip points?
A: Absolutely. The overvoltage trip point is adjustable from 230V to 300V (default 270V), and the undervoltage trip point from 140V to 210V (default 170V). The overcurrent limit is also adjustable within the model's rated range, giving you full flexibility to tailor protection to your specific circuit needs.
Q: What does the dual digital display show?
A: The large dual digital display simultaneously shows real-time working voltage and current, allowing you to monitor your circuit's live status at a glance without any additional measuring equipment.
