Product Description
Ordering Key
The SOLITRON Midi is a sin-
gle-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. For cur-
rent rating of 75AACrms
(AC51) convection cooling is
used. The standard housing
dimensions enable straightfor-
ward replacement of alterna-
tive products and the terminal
layout allows both contactor
(E) and SSR (U) type connec-
tion. Cage clamp terminals
are used to ensure secure load
connection with cable up to
25mm
2
.
An LED indicates the status of
the control input. The superior
heat-transfer efficiency com-
bined with a robust power
management system make
this a high reliability product
that can meet the most strin-
gent functional requirements.
