Product Description
Ordering Key
The SOLITRON Mini is a single-phase Solid State
Contactor designed to replace
electro-mechanical contactors
in industrial heating and motor
applications, especially when
switching is frequent. The
product is ready to mount on
DIN-rail or chassis and comes
with integral heatsink. The
standard housing dimensions
enable installation in limited
space and the terminal layout
allows both contactor (E) and
SSR (U) type connection. Two
2.5mm
2
cables can be connected in each screw terminal
to allow looping. A removable
IP20 cover allows connection
of a 4mm
2
cable with crimped
terminal. An LED indicates the
status of the control input.
The superior heat-transfer efficiency combined with a robust
power management system
make this a high reliability
product that can meet the
most stringent functional
requirements.
