General Purpose Contactors
Handling of the contactors
S-N10CX to S -N65CX units can all be mounted
on DIN rail (35 mm wide).
A variety of auxiliary blocks and optional featu-
res are available including:
앬
Standard front clip-on auxiliary contact blocks
(4-pole-type and 2-pole-type)
앬
Low-level signal front-clip-on auxiliary con-
tact blocks
앬
Side clip-on auxiliary contact blocks
앬
Surge absorbers (varistor and CR models)
앬
Surge absorbers with LED operating indicators
앬
Mechanical interlocks
Compact arc quenching and magnet layout
greatly reduces installation space.
The coil rating is displayed in a location readily
visible even after the unit is installed onto the
panel.
Contacts are visible when the cover is removed,
allowing them to b e checked easily.
Compact, modular extensions and an
energy-saving design – these are the
main requirements set by users of
contactors and auxiliary contac tors.
Requirements that the MS-N series from
Mitsubishi Electric fulfill.
