DIHOOL Smart Circuit Breaker with Adjustable Voltage Protection | 70–200V Low / 140–300V High | 1–63A DIN Rail Mount

DIHOOL Smart Circuit Breaker: Adjustable Voltage Protection

Power runs behind the scenes in homes and small workplaces, driving everything from laptops to kitchen gadgets. The DIHOOL Smart Circuit Breaker acts as a protective shield, delivering precise, customizable protection against voltage fluctuations and current surges. With up to 19 presets, you can tailor responses to your environment while enjoying a clean, intuitive interface that keeps setup approachable for everyone.

Precision you can rely on

Designed for modern electronics, this protector supports adjustable overvoltage and undervoltage thresholds along with a wide overcurrent range. Set high and low voltage cutoffs (for example 130–300V overvoltage, 80–210V undervoltage) and current protection from 1 to 63A. When an abnormal condition is detected, it disconnects automatically to protect connected gear, then returns to normal once conditions stabilize.

Smart, automatic recovery

There’s no need to intervene every time the power dips or spikes. The device monitors power quality and restores supply automatically when safe levels return, helping minimize downtime for essential devices.

Durable, safety-first design

The outer shell uses fire-resistant PC material and has been rigorously tested to help reduce fire hazards. Coupled with automatic disconnection, this creates a robust barrier for valuable electronics and home systems.

Easy installation on a standard DIN rail

With a universal 35mm DIN rail mount and quick-attach design, you can install the protector in minutes inside electrical panels, control cabinets, or consumer units. It’s compatible with common layouts and ready to integrate with existing protection schemes.

What you gain in daily life

From a gaming PC to a multi-device home setup, the DIHOOL protector guards against abrupt voltage shifts and current spikes, helping reduce unexpected shutdowns and equipment wear. It’s a single, scalable shield for a broad range of devices.
