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 selfextinguishing polypropylene.
bb 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.
bb 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.
bb 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.
20 units (except for ref. NSYS95100: 10 units)
Terminals specially designed for the
Entry by plate and junction by cable, plate or
junction of cables on plates, their main terminal.
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).
