LSA-Plus surge protection

LSA-Plus surge protection from OBO is used es-
pecially with multi-wire systems such as those to be
found, for example, in measurement and control en-
gineering and in telephone exchanges. For example,
ten two-wire (TC) systems can be protected with only
one surge protection (basic protection) magazine
LSA-B-MAG. Modules LSA-BF provide one twin-core
protection of two lines.
The basic and precision protection devices of type
LSA-BF 180 (180 V version) are intended for use in
telephone exchanges in analog and ISDN networks.
OBO basic and precision protection devices
LSA-BF-24 (24 V version) are used especially in
computer systems and measurement and control
engineering.
The protection circuit of the LSA-Plus devices consists
of powerful triple-pole gas discharge arresters. Basic
and precision protection are based on fail-safe tech-
nology, ensuring that, in the event of a thermal over-
load, the arrester is bridged and therefore protected.
Mounting
The LSA connection or isolating strips are fixed simply
by snap-fitting to a mounting tray. This means that
they can be mounted on almost any wall.
