FBMOV Series - Thermally Protected and Non-Fragmenting Varistor.

The Littelfuse FBMOV Series thermally protected and Non Fragmenting varistor represents a new development in circuit protection. It consists of a 40kA varistor building block (MOV) with an integral thermally activated element designed to open in the event of overheating due to abnormal over-voltage, limited current conditions.

FBMOV series devices also include a varistor series fuse which prevents the part from rupturing when subjected to high fault current (up to 200kA).The tubular fuse-like body allows for easy mechanical connection in the application.

Another feature of FBMOV is an indicator lead, which may be connected to monitoring circuitry and used to signal if the MOV has been disconnected.

FBMOV series devices offer quick thermal response due to the close proximity of the integrated fusing thermal element to the MOV body. The integrated configuration also offers lower inductance than most discreet solutions resulting in improved clamping performance to fast over-voltage transients.

Applications:
  • Type 1 SPD (Surge Protection Device) Products
  • Power supplies
  • Transformer
  • Residential Service Panel
  • Power distribution
