)

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.
