elecworks – Terminal Blocks with Electronic Components

By Miles Nicholson

IEC60617 defines the symbology required for drawing electrical schematics but sometimes the standard does not go far enough. An example would be a terminal with electronic components bridging connections or even connected across levels. How should these be drawn in a schematic? This is our interpretation.

The above shows from left to right: solid link, fuse, resistor, diode, diode180, LED, LED180, test link terminals.

The above shows from top to bottom: LED, LED180, fuse, resistor, diode, diode180, test socket, varistor cross connections. 

When used in combination, the 2nd terminal is defined as the 2^nd deck of the first terminal.
