In modern power distribution networks, safety is not just a requirement—it is a foundation. As electrical infrastructures expand and become more complex, the demand for reliable Non-Fire Electrical (NFE) safety components continues to grow.
NFE safety components are specialized electrical fittings designed to ensure that power distribution equipment operates safely without generating excessive heat or fire risks. These components play a crucial role in low voltage (LV), medium voltage (MV), and fiber optic communication networks.
Typical NFE components include:
These products are engineered to maintain stable electrical connections while preventing overheating, short circuits, or ignition sources.
At Jera Line ,we specialize in designing and manufacturing high-quality NFE components that protect electrical systems from overheating, arcing, and potential fire hazards.

Features
Metal oxide surge arresters are commonly used in electrical networks and devices to protect them from high-voltage surges. The metal oxide semiconductor material in the arrester acts as a resistor, and it's designed to absorb energy from any surge of voltage or current that exceeds safe levels.This helps prevent damage to sensitive components and equipment.
Surge Arrester SA-0.28/10 is a voltage and current protector,it features functions such as overcurrent, overvltage and undervoltage protection. When the current/voltage deviates from the set value,the relay automatically disconnects the power to prevent fires and safeguard electrica devices, it also has an auto-reset function, which means that when the voltage and current return to normal values, the power is automatically restored.
Besides,Jera Line can provide other type of Surge arrester for option.
Yuyao Jera Line has over a decade of experience serving global utility companies, EPC contractors, and electrical distributors. Our NFE components are produced under strict quality control systems such as ISO 9001, ensuring each product meets international safety standards.
