Fusible disconnect switches
OS60 and OS100 Gamma range
OS Gamma fusible disconnect switches
ensure safe operation, protecting both
people and equipment even in extreme
conditions.
Designed for safety
Designed and based on substantial experience of electrical
safety, OS Gamma fusible disconnect switches eliminate the
risk of electrical accidents:
−
The interlocking fuse covers prevent opening while the fusible switch is in the ON-position and can be sealed in the
closed position.
−
Double insulated external operating handle that eliminates
the risk of touching live parts outside the box.
−
Reliable contact position indication in all situations.
−
Frame made of robust plastic, with excellent mechanical
and thermal properties.
−
Voltage output pins as standard.
−
Pole markings as standard.
• You take no risks with OS Gamma range.
Superior performance
−
Smart design, with optimal contact constructions.
−
High insulation ratings
−
OS Gamma fusible disconnect switches meet the requirements to be installed close to the main transformer: up to
200 kA in heavy industry and in ships.
Easy installation
−
Adjustable mounting feet that allow top and side mounting.
−
Mounting the cables is simple thanks to high terminal positioning with space to the back plate. This is also ideal for
double cabling, which in turn saves space.
• Flexible and time-saving installation
Compact construction
−
An intelligent construction in combination with a small number of components results in a very compact mechanism
design.
−
Very small footprint area.
• Space savings mean cost reduction
A wide selection of accessories improves the usability of the
fusible switches.
• Suitable for all applications in low voltage networks
