CZVA3 EU Plug 16A Voltage Protector Socket Dual Display Voltage Current with Password Lock

Protecting an appliance from voltage anomalies is straightforward. Knowing your circuit's live current draw at the same time, locking your protection settings so no one can change them, and cutting power within half a second of a fault — that requires a more capable device. The Soltree CZVA3 is designed for users who need more than basic voltage protection.

Its high-resolution dual-color digital display shows voltage in red and current in green simultaneously, giving you a real-time snapshot of both grid quality and load behavior without switching between screens or menus. Over-voltage and under-voltage trip thresholds are fully adjustable (130–300V and 80–210V respectively), and over-current protection adds a third layer of defense for appliances susceptible to load spikes. The password lock function prevents unauthorized changes to protection settings — critical for shared accommodation, rental properties, or small business environments where multiple people have access to the device.

Rated at 16A / 3680W, it handles higher-draw loads that exceed the capacity of standard 10A plug protectors — large washing machines, powerful electric heaters, workshop tools. The wider operating temperature range (-25℃ to +55℃) and multi-frequency support (40/50/60/70Hz) make it suitable for environments beyond the typical household. Flame-retardant UL94 V-0 housing, ≥10,000 mechanical cycle rating, custom LOGO available for OEM orders.
