20FM781K Zinc Oxide Varistor

20FM781K Zinc Oxide Varistor

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 14.

Features

ed, 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 company logo. Example: MDC FV 14N201 Where: MDC - Company 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.
