DIL contactors, 3-pole – System overview

Innovations with xStart


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
  • 4 sizes cover the performance range up to 170 A
  • Only 3 widths up to 170 A
  • Integrated auxiliary contacts

 

Mounting
  • Twin 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 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.

coil connections

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

box terminal 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.

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 geometries. This facilitates a common range of accessories which is independent of the voltage.

Operation

AC equal DC 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.
