Product Description

The Single Phase Dual Display Over Under Voltage Protector from Zhejiang Chenhai Electric offers comprehensive Electrical Safety with power‑on delay, overvoltage protection, undervoltage protection, overcurrent protection, and adjustable delays for over/under voltage and overcurrent. Rated at 63A and 50‑500V, it is ideal for residential, commercial, and light industrial applications. The built‑in dual display shows real‑time voltage, current, and accumulated energy (kWh), allowing users to monitor power quality at a glance. DIN rail mounting and compact dimensions (87×39×68 mm) enable easy installation in distribution boxes. This protector automatically disconnects the load when voltage or current exceeds safe limits, then reconnects after a preset delay when conditions normalize. It effectively prevents damage to sensitive equipment such as air conditioners, refrigerators, pumps, and industrial controls. For complete electrical system protection, use it alongside Circuit Breakers to handle short circuits and overloads. Integrate it with Power Meters & Rail‑mounted Energy Meters for detailed energy auditing and cost allocation. In advanced automation systems, pair it with Microcomputer Protection Devices for grid‑facing protection or with Surge Protectors to guard against voltage spikes. The device also works well with Digital Pressure Gauges & Transmitters in hydraulic or pneumatic systems where pressure and voltage need coordinated monitoring. Unlike simple voltage relays, this protector offers dual‑display readouts, programmable delay times, and kWh measurement, making it a versatile choice for panel builders and facility managers. The 63A rating supports direct connection of most household and small industrial loads. The 50‑500V wide voltage range accommodates global single‑phase standards. The transparent housing allows visual inspection of internal components. With its robust design and easy wiring, this over under voltage protector reduces downtime and prevents costly repairs. Choose Zhejiang Chenhai Electric for reliable, intelligent voltage protection that combines measurement, display, and automatic control in one DIN‑rail package. Upgrade your electrical safety with this dual‑display protector today.
