SFEX MC4 Cover is a dedicated automatic fire suppression device designed to enclose MC4 connectors, which are widely used in solar power systems. In the event of a fire, it suppresses flames and prevents fire propagation through a patented dual-action extinguishing mechanism that combines cooling and oxygen-deprivation suppression, enabling rapid and effective control of fires at their earliest stage.
MC4 Connector-Specific Design
Designed to securely enclose the entire connector, the cover activates fire suppression immediately upon fire detection, preventing fire spread and helping contain incidents before they escalate into major fires.
Dual-Action Fire Suppression Mechanism
In the event of a fire, the integrated fire suppression sheet simultaneously performs cooling-based and oxygen-deprivation suppression, effectively eliminating fire at its source and preventing further propagation.
High-Performance Flame-Retardant Material (EPDM)
Manufactured from premium EPDM material that achieves top-tier flame retardancy with a UL94 V-0 rating. It delivers exceptional weather, ozone, heat, and chemical resistance, maintaining stable performance even in harsh outdoor environments.
Patented Dual-Action Suppression Mechanism
This system maximizes fire extinguishing efficiency by combining patented cooling suppression (Patent No. 10-2402409) and smothering suppression (Patent No. 10-2417215) technologies.
Excellent Insulation and Protection
Leveraging the inherent properties of EPDM, it provides outstanding insulation performance to effectively prevent electrical fires while shielding the connector from external physical impacts.
