Boîte de distribution blanche avec parafoudre 60KA 4P 385V IP20, coffret de combinaison simple et sûr, parasurtenseur pour installation électrique

Protect your electrical equipment with this high-performance surge protection device, designed for reliable and safe operation in a variety of installations. Below are the key features and specifications to help you make an informed choice.

**Working Mechanism:**

When a surge overvoltage occurs due to lightning or other causes, this protector activates within nanoseconds, quickly diverting the surge to the ground. This safeguards your connected devices from damage, and after the surge passes, it automatically returns to a high-resistance state, ensuring uninterrupted normal operation.

**Insulated Terminal:**

This device features a plug-in design that supports hot-line operation, making installation and maintenance easier. The insulated terminals provide reliable and safe connections, with rapid response time and strong load-bearing capacity.

**Condition Indication Window:**

A clear status window shows the working condition: green indicates normal operation, while red signals a fault. This allows for quick visual inspection and timely maintenance.

**Fireproof and Corrosion Proof:**

Constructed with fireproof and corrosion-resistant materials, this surge protector remains stable under various conditions, effectively responding to the working status and ensuring long-term durability.

**Material and Build:**

Made from flame-retardant PC material with fine craftsmanship, this device is easy to use and simple to install via standard guide rails.

**Main Structure and Operating Principle:**

In a three-phase four-wire system, the protector connects between the three phase lines and the neutral wire to ground. Under normal conditions, it remains in a high-resistance state. When a surge overvoltage occurs due to lightning or other reasons, it conducts rapidly within nanoseconds, directing the overvoltage to the earth and protecting your grid equipment. Once the surge disappears, it reverts to high resistance, preserving normal grid operation.
