Surge Arrester

JMV Earthing Equipment offers a Surge Arrester Class C Type with NPE V. This is a protective device designed primarily for connection between a conductor of an electrical system and ground to limit the magnitude of transient over voltages on equipment. A lightning arrester is a voltage surge arrester. The voltage dependent active part of the BDL/C/40. NPE is a high-performance zinc oxide varistor with a highly non-linear characteristic. Among the advantages of this component are an extremely short response time, a low protection level and a high current diversion capacity, combined with long life. A further feature of these devices is that no follow-up current can be registered after the surge has decayed.
Advantages:

• Metal-oxide varistor arresters still work after frequent operation.
• An arrester module can be changed with the mains voltage on.
• 1-4 pole blocks simple installation via the marked terminals.
• Thermal isolating device with optical indication.
• Permanent check of arrester serviceability.
• IT and IT systems that no voltage can reach the protective earth (PE) conductor.
• Simple, professional installations of the arrester modules.
