Contactors covers the performance range
up to 170 A with four sizes and three
installation 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
DILM 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.
Moeller also offers the tried and
trusted quality in the area of
spring-loaded terminals. Up to 12 A the
main and control circuit terminations
and from 12 A the control circuit
terminations are available with
spring-loaded terminals.
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 spring-loaded terminals can
be implemented much faster.
Contactors with DC and AC operation
now have identical geometries. This
facilitates a common range of
accessories which is independent of the
voltage.
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 under voltages and over
voltages.
