Feature:

1. STVP series automatic reset over-voltage under-voltage multi-function protector is a monitoring and auxiliary protection device instrument suitable for three-phase four-wire power system or electrical equipment

2. When the line has overvoltage, undervoltage, or overt status, this product can instantly cut off the power supply to protect the electrical equipment from being damaged; when the line voltage returns to normal, the protector can automatically turn on the power supply normally

3. This protector integrates over‑voltage protection, under‑voltage protection, over‑t protection, three‑phase t (voltage) unbalance protection, phase sequence protection (phase dislocation protection), and phase‑break protection in one

4. The product has the function of fault inquiry, voltmeter and ammeter, and the function of restoring factory settings

5. Adjustable voltage protector come with complete functions, stable performance and easy operation
