Schematic diagram of U35 heating system
System example 1 - Simple heating
The simple principle of conductor rail heating consists of an infeed terminal and an outfeed terminal, a heating
wire and a connection box.
1 Heating infeed terminal
2 PTC thermistor
3 Connection box / heating conductor control
4 PTC thermistor
5 Heating infeed terminal as "outfeed terminal"
6 Heated part of the conductor rail (heating wire)
System example 2 - Heating with pole change via PTC thermistor bridge
In order to generate a pole change, PTC thermistor bridging can be implemented. Instead of proceeding as in
example 1, the heating wire can also be bridged on an opposite pole and fed back.
