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 ponents 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 ponents 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 ponents 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 leaded, thermal fuse on outer lead FT - 3 leaded, fusible link on outer lead 3. AC Voltage Rating Two significant figures plus number of zeroes that follow, i.e. 201 is 200 VDC 4. Varistor Voltage Range Tolerance STANDARD MARKING Minimum marking shall consist of an abbreviated style designation and, when space is available, the manufacturer’s initials or pany logo. Example: MDC FV 14N201 Where: MDC - pany Initials FV - Fail safe Varistor 14 - Diameter N - Series (FN, FM, FE, FF, FT) 201 - Nominal DC Voltage Rating (200VDC) A manufacturing date code and/or special markings are available upon request. Other safety agency designations are included where applicable. Maida Development pany - sales@maida. - (757) 723-0785 - .maida.
