| The newly developed DILM
contactors switch motors up to 170 A.
Significantly improved performance features
such as pickup and holding powers, optimised
dimensions and advantages during
installation transform the contactor relays
to an absolute top product.
Engineering

 |
|
- Only 4 frame sizes instead of 7
- Only 3 widths up to 170 A
- Integrated auxiliary contacts
- Only a single contactor relay size.
Mounting
|
|
|
- Box terminals with contactors from 7 A
to 170 A
- Coil connection located at the front
- AC and DC contactor relays have the
same dimensions.
Operation

- Integrated suppressor with DC operated
contactors
- AC suppressor is simple to plug-in
- Low holding powers with DC contactor
- DC universal voltage coils from 17 A.
Engineering
Moeller has reduced the number of
variants from seven to four frame sizes with
just three differing widths (45 mm up to 32
A, 55 mm up to 72 A and 90 mm up to 170 A).
The smallest frame size as a contactor relay
and contactor is an excellent compromise
between minimum dimensions, higher physical
performance capability and additional
handling advantages.
Contactors are devices for
world markets. They have UL and CSA
approvals..
As the main circuit wiring is generally
implemented first in power distribution
systems using thick wiring and solid wiring
cross-sections, the coil connections which
have been moved forward play their part in
assuring rational wiring.
Mounting
DIL contactors up to 170 A feature box
terminals with two clamping chambers.
Differing conductor cross-sections can be
safely wired – even on machines subject to
strong vibrations – using this feature.
Wiring is made easier and wiring fault
potential is reduced.
Moeller also offers the tried and trusted
quality in the area of springloaded
terminals. Up to 12 A the main and control
circuit terminations and from 12 A the
control circuit terminations are available
with springloaded terminals.
Numerous tests prove that contactors and
motor-protective circuit-breakers can be
just as safely wired in this manner as with
screw terminals – even on machines subject
to extreme vibration. However, wiring with
springloaded terminals can be implemented
much faster.
Contactors with DC and AC operation now
have identical geometry's. The performance
of the device actuation and the ratio of
switched output power to the required
auxiliary power has been improved
significantly.
Operation
All DC operated contactors also have an
integrated suppressor.
The actuation voltage tolerance of the DC
operated contactors exceeds the requirements
of the IEC standards and provides optimum
protection with undervoltages and
overvoltages.
