Overview

THERMALLY PROTECTED SERIES INTRODUCTION The Thermally Protected Series is designed for safe disconnection of the varistor from the circuit due to abnormal operating conditions.
These components consist of 2 or 3 leaded wire leads, a thermal disconnect (FN, FM, FN), and have nominal diameters of 14mm, 20mm, and 25mm.
Fusible link designs (FF, FT) are also available.
STYLE DESIGNATION The Maida Style Number is the typical means to identify our components when ordered.
The style number identifies several parameters that are important for the characteristics of the device.
An alternative ordering method, if known, is by our Item Number.
The following example is the standard part numbering system when ordering our Thermally Protected Series components by the Maida Style Number: 14 FN 201 K 1.
Nominal Disk Diameter 14 – 14mm 20 – 20mm 25 – 25mm 2.
Lead Configuration FN – 2 leaded, thermal fuse FM – 3 leaded, thermal fuse on center lead FF – 3 leaded, fusible link on center lead FE – 3 lead...
