Plate/cable terminals
Safety terminals made from self-extinguishing
Polyamide-6, with matt black base, MS-58
brass terminal (DIN 17660), tempered,
zinc-plated and dichromated steel ring, and
cover made from orange-coloured self-
extinguishing polypropylene.

Anti-shearing: the connection is made by
means of a tightening mechanism, which
distributes the pressure across the entire
contact surface, avoiding friction and
occasional stress that can damage the
conductors.
b
b
Unloosenable: the ring that surrounds the
brass body guarantees that the pressure
exerted by the actual conductors cannot open
the terminal and loosen the connection.
b
b
Full insulation: all the SIGMA "S" terminals
are supplied with a terminal-covering cap,
avoiding any accidental contact with live parts.
All the gauges can be coupled together, forming
strips of any length. Operating voltage: 500 V.
Terminals specially designed for the
junction of cables on plates, their main
application is in busbar connections.
The bimetal terminals are made from a
copper alloy, hot-stamped and tin
plated, suitable for connecting a copper
or aluminium conductor indistinctly
(bimetal).
Entry by plate and junction by cable, plate or
terminal.
Supply
