Jera Line offers the following LV surge arresters, also known as Metal Oxide Surge Arresters (MOSA), which are designed for overhead lines and distribution transformers.
• Fast Response Time
• No Power Frequency Follow Current
• Auto-reset Function
When the voltage and current return to normal value, the power will be automatically restored.
• Long Lifespan
Typically lasts 20-30 years with proper maintenance.
• No need any voltage grading systems
• Protecting from both overvoltages and under-voltages
• Protect the components of electrical systems
• Indicate the system fault through the LED light
Protecting residential or commercial appliances, solar inverters, and LV distribution panels.
When the current/voltage exceeds or below the set value, the relay automatically disconnects the power to prevent fires and safeguard electrical devices.
When the voltage/current return to normal values, the system is automatically restart.
Jera Line produce low voltage surge arresters in accordance with IEC 61643, which has various testing demands for reliability, mechanical and environmental performance, safety and operational behavior.
Jera line produces low voltage insulation piercing connectors that can be used with surge arrester.
