ABB LOVOS-5 & LOVOS-10 Low Voltage LV Surge Arresters

 

ABB low voltage surge arresters LOVOS-5 and LOVOS-10 are a new generation of LV surge arresters ensuring electrical protection of overhead lines, electric energy receivers, distributing transformers and low voltage electrical equipment. Specify and install ABB LOVOS type surge arresters to protect low voltage power equipment from the effects of lightning and switching overvoltages.

Applications for Low Voltage LV Surge Arresters

The ABB LOVOS range provides protection along LV overhead lines, cables, motors, switches, any equipment connected to the line, from the LV side of distribution transformers up to measuring instruments. The LOVOS surge arresters are suitable for indoor and outdoor applications and for altitude up to 2000m over sea level. Also for use in ambient temperature in place of work or storage from -40°C to +70°C.

ABB LOVOS-5 & LOVOS-10 Low Voltage Surge Arrester Advantages

• Easy assembly and connection
• Disconnecting device simultaneously fulfilling the function of damage indicator
• Large choice of accessories
• Casing resistant to UV radiation, non-flammable
• Maintenance-free product
• All accessories are made of corrosion-resistant materials
