قاطع دارة كهربائية ثلاثي (MCN320) قياس (20)أمبير من (Hager)

Key features include a three‑phase, 20A rating, thermal‑magnetic overcurrent protection for safety, a slim and lightweight design for easy installation, and insulation plates that protect against air humidity. It’s also described as suitable for all climates without needing an extra spacing cover.

Core specs: 3‑phase operation, 20A current rating, thermal‑magnetic trip mechanism, humidity‑resistant insulation, slim profile for easy installation, and certification to European safety standards.

It means the insulation and design help prevent moisture-related issues, so the unit can be installed in environments with higher humidity without needing extra protective spacers or covers.

The breaker incorporates insulation plates that shield critical parts from air humidity, reducing the risk of moisture-related malfunctions and improving reliability in humid or damp environments.

The MCN320 is designed for standard panel installations where three‑phase protection is required. It features a slim, lightweight build to facilitate straightforward mounting in typical electrical panels or enclosures.

Ideal for three‑phase electrical systems needing reliable overload and short‑circuit protection, such as industrial control panels, motor circuits, and other equipment in environments with varying humidity.

If the circuit is overloaded or a short occurs, the MCB will trip to the OFF position. To reset, switch it back to ON after correcting the fault condition and verifying all connections are secure.

Yes, it’s designed with ease of installation in mind. Its slim form factor and clear trip/reset operation help simplify replacement or upgrade in compatible three‑phase panels.

The product description emphasizes the humidity‑protected design and installation simplicity. For accessories or mounting adapters, check related product listings on Fepy for compatibility notes and options.

Consider your three‑phase system needs (20A rating), the environmental conditions (humidity tolerance), panel space and mounting, and the need for thermal‑magnetic protection. Also weigh the European safety standards compliance and the unit’s compact, lightweight design when planning installation.

At the moment, there aren’t specific direct 3P 20A MCB alternatives listed on Fepy for an exact one‑to‑one comparison. If you’d like, I can help you identify other three‑phase MCB options on Fepy that suit your requirements and provide their pages.
