KOA Speer's New Varistor Series Offers Surge Current Protection Up to 6,000A NV73S Series

NV3S Bradford, PA - July 23, 2024 - KOA Speer Electronics introduces the NV73S series multilayer type metal oxide varistor that handles a surge current of up to 6,000A, which is five times higher than existing products. The multilayer construction can absorb a large surge despite its small size. The two-way symmetries can absorb positive and negative surges. The NV73S replaces the NV732E (1210) through 2L (2220) due to its improved surge protection.

Maximum peak current and sizes for the new NV73S are 400 to 800A (1210), 500 to 1,200A (1812), and 1,500 to 6,000A (2220) with a working voltage range of 6 to 95V (ac) and 9 to 127V (dc). The varistor voltage range for the NV73S series is 12 to 150V.

The new NV73S series metal oxide varistor offers protection from ESD (electrostatic discharge) and EMI (electromagnetic interference) for electronic devices. It also provides surge protection for motors, relays, and solenoid valves.

The NV73S varistor series meets EU-RoHS requirements. Lead time is 10 weeks. Samples are available upon request.
