Diameter 14mm Thermal Varistor

1. Thermal cut-off 
2. Diameter 14mm,  cross to LITTELFUSE's TMOV or iTMOV series
3. AC voltage 300Vac;
4. Varistor voltage 510V +/-10%
5. Peak Current: 4500A / 6000A
6. RoHS compliant
7. TMOV series varistor is a type with over temperature cut-off functions. A Temperature fuse is connected with MOV in series. When the operating current increasing continuously or MOV failure, the temperature fuse will be cut-off because of the temperature over the limit.

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.
