3K Load-Break Switches –
The Program for
Safety and Performance
sentric
Whether for reliable switching and isolation under load, or for protection
against overload or short-circuits – our 3K range of load-break switches
cannot be beaten when it comes to safety, performance and reliability.
We have versions with and without fuses, a full range of accessories, right
up to special enclosures for the toughest of environments – a comprehensive switch range for any eventuality.

3K load-break switches – the reliable device for every eventuality
3K load-break switches are proven devices for the distribution of energy in domestic and commercial buildings as
well as in applications in industrial switchboards, motor
feeders or variable-speed drives.
Thanks to their compact construction they can be optimally
installed in any distribution system. The 3KA and 3KE
switches can be used for all main, EMERGENCY STOP, maintenance, and changeover switch requirements.
The 3KL and 3KM ranges with integrated fuses protect
against the damaging effects of overloads and shortcircuits. They can be fitted with IEC or BS fuses, for protecting frequency converters or for fast installation on 3KM
busbars. Above all, the line-side fuse always gives reliable
protection from short circuits. Another advantage is that
the 3K program is available complete as safety switch with
high-quality 8HP insulated enclosure (IP 65) – which
means even more possibilities for high-performance safety
concepts.
The 3KA and 3KE ranges of load-break switches
– without fuses – can be used in distribution
boards in residential and commercial buildings
and in industrial switchboards. With 3 or 4 poles,
they take care of reliable isolation and switching
under load at rated current. Hence, they are
ideal for all main, EMERGENCY STOP, maintenance, and changeover requirements. And
they guarantee safe isolation in all low-voltage
circuits.
The 3KL and 3KM load-break switches – with
fuses – also afford protection from the effects of
overload and short-circuit, which makes them
ideal as main and EMERGENCY STOP switches for
switchboards, distribution boards and motor
feeders. Equipped with Siemens SITOR semiconductor fuses, they are also capable of meeting
the highest requirements, such as UPS systems,
variable-speed drives or power-factor correction
systems.
The design of 3K means that every switch offers
a double break on the contacts and thus on the
isolating distance. When the switch is in the OFF
position, the fuses are dead. For additional safety, each switch can be locked in the OFF position
by means of a padlock at the shaft.
In the case of 3KM switches – with fuses – an
isolating plug connector makes installation a
simple matter without the need for tools. This is
an advantage in MCCs, for example, for making
the contacts with vertical busbars.
The same range of accessories for 3KA, 3KL and
3KM – with and without fuses – saves storage
space and makes spares easier to find.
The two 3K ranges: Load-break switches
with and without fuses
For service in extreme environments, we supply
the 3K special range of switches, for such applications as 63 A to 630 A safety switches in 8HP
insulated housings (IP 65), and switches that are
resistant to the aggressive atmospheres found in
sewage treatment plants, chemical plants, or
the pulp and paper industries.
All 3K load-break switches are climate-proof and
comply to the requirements of IEC 60 947-1, IEC
60 947-3, DIN VDE 0660 Part 107, EN 60 204-1,
IEC 60 439, EN 60 439, DIN VDE 0660 Part 500.
