40kA Varistor

40kA Varistor

Varistors are voltage-dependent resistors with a symetrical V/I characteristic curve whose resistance decreases with increasing voltage, connected in parallel with the electronic device or circuit that is to be guarded, they form a low-resistance shunt when voltage increases and thus prevent any further rise in the overvoltage.  KVR varistor is sintered zinc ovide together with other metal oxide additives under specific conditions. Which produces a ploycrystalline ceramic whose resistance exhibit a pronounced dependence on voltage.  Kestar factory has ISO9001:2008 certificate and ISO14001:2004 certificate. The products have UL, CSA, CE, VDE, CQC approval. All products are RoHS compliant. 1. Diameter 34mm, square shape 2. H type terminal, Flat 3. AC voltage 460Vac; 4. Varistor voltage 750V +/-10% 5. Peak Current: 40000A 6. CE, UL approval 7. RoHS compliant 8. The products are widely used in builing outdoor leading-in wires (such as, switch), mining, petrolatum equipments, power supply control, power transmission, telecommunication, networks, railway, motor control, etc.
