63A 220V Din Rail Digital Voltage Protector Relay | Over/Under Voltage

63A 220V Din Rail Adjustable Digital Voltage Protector Relay

Keep your electrical circuits and appliances safe with this robust 63A 220V Din Rail Adjustable Digital Voltage Protector. Designed for both residential and light commercial applications, this intelligent protection relay continuously monitors incoming voltage and current, automatically disconnecting the load when unsafe conditions are detected — then reconnecting once conditions return to normal. A clear digital display lets you monitor live voltage and current readings at a glance.

Made in Mainland China.

Key Features

• Over-Voltage Protection: Automatically cuts power when voltage rises above your set upper limit, safeguarding connected appliances and equipment.
• Under-Voltage Protection: Disconnects the circuit when voltage drops below your preset lower threshold, preventing damage from low-voltage conditions.
• Over-Current Protection: Monitors current draw and trips the relay when current exceeds the adjusted limit — an extra layer of circuit safety.
• Adjustable Set Points: Easily program your own over-voltage, under-voltage, and over-current thresholds to suit your specific installation requirements.
• Automatic Recovery / Reset: Once voltage and current return to within safe, programmed limits, the device automatically reconnects power — no manual reset required (manual reset mode also available).
• Live Digital Display: Real-time voltage measurement and current measurement shown on the built-in digital screen for instant visibility.
• DIN Rail Mounting: Standard DIN rail compatible for neat, secure installation inside electrical panels and enclosures.
• Rated Capacity: 63A / 220V — suitable for high-load single-phase circuits.

Frequently Asked Questions

Q: What does this 63A 220V voltage protector relay do?

A: This DIN rail voltage protector continuously monitors your electrical circuit's voltage and current. When voltage rises above or drops below your programmed thresholds — or when current exceeds your set limit — it automatically disconnects the load to protect connected appliances and wiring. Once conditions return to safe levels, it can reconnect automatically or await a manual reset, depending on your setting.

Q: Can I adjust the over-voltage and under-voltage trip points myself?

A: Yes. The device features user-adjustable set points for over-voltage, under-voltage, and over-current limits. You can program these thresholds to match your specific installation requirements using the onboard controls.

Q: Is this device suitable for home electrical panel installation?

A: Yes, it is DIN rail mounted, making it compatible with standard residential and commercial electrical enclosures and distribution boards. We strongly recommend installation by a licensed electrician to ensure compliance with local electrical safety codes.

Q: Does the digital display show real-time readings?

A: Yes. The built-in digital display shows live voltage and current measurements, so you can monitor your circuit's status at any time without additional meters.
