New! TFD 101 Telecom Fused Disconnect

•   TFD 101 - 80 Vdc, 1 to 125 Amps           Now Available in 125 AMP Rating  
  
  

  The TFD-101 is the versatile alternative for low voltage, high current telecom systems. Use normal wiring methods or front-mount in place of circuit breakers in a panel. Plug-in connectors eliminate the need for installation tools. Other connection methods are also available.

  The TFD-101 is designed to protect telecommunications circuits. It also provides a visual and remote warning that an overload condition has occurred.

  Rear mounting to your system with bullet type terminals is standard but optimal screw type terminals are available. Front panel mounting is also integral to the TFD-101 design.

  The economical replaceable fuses are located in a removable cartridge accessible from the front of the unit. This compact fused disconnect is physically and electrically interchangeable with expensive circuit breakers.

  Heat sink mountable design with non-inductive performance, featuring an exposed copper heat dissipating mounting surface electrically insulated.

  Use your thermal design experience with power semiconductors. This experience will help you get the most out of this unique family of high performance (Hi-Per) Shunts.

  The thermal design issues are the same where the power handling capability is based on the case temperature which is maintained in your design.

  Resistor element is electrically isolated from the mounting metal heat sink surface.

  The case temperature is to be used for the purpose of establishing the maximum applied power.
