MC4 PREMIUM 6mm Cover
Fireproof cover for MC4 connectors – passive fire protection for photovoltaic installations
The MC4 PREMIUM shield is a professional protective solution designed to increase the safety of photovoltaic installations by passively protecting MC4 connectors against fire . MC4 connectors are one of the most common fire hazards in PV installations because, with direct current , the electric arc does not self-extinguish , which can lead to overheating and ignition.
The most common causes of arc flash include loose connections, contact corrosion, mechanical damage, or overheating of wires . The MC4 PREMIUM fireproof enclosure was designed to limit the effects of such incidents and protect the photovoltaic installation from spreading fire.
The product operates completely passively , meaning it requires no power supply, sensors, or electronics. If a flame develops inside the connector, the flame-retardant housing isolates the fire and limits oxygen access, while the metal internal inserts suppress flame growth , preventing it from spreading to other components of the system.
An additional external coating that reflects thermal radiation limits the heating of the joint and improves the stability of the installation in difficult weather conditions.
The MC4 PREMIUM cover is compatible with standard MC4 connectors used in photovoltaic installations , so it can be used both in new PV installations and when modernizing existing systems.
This solution provides passive fire protection for photovoltaic installations , increasing the safety of residential and industrial buildings and energy infrastructure.
