Engineering and Mounting

Engineering
  • Only 4 frame sizes up to 200 A
  • Integrated auxiliary contacts up to rated currents of 45 A
  • Identical frame sizes with AC and DC operated contactors
  • Common range of accessories for 3-pole and 4-pole contactors.

Monting
  • Box terminals up to 200 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

Optimum dimensions are a compromise between minimum frame sizes, higher physical performance capacity and additional handling benefits.

coil connections

Contactors are device for world markets. They have for example, UL and CSA approvals.

As on switchgear systems the main wiring is generally implemented first – often with thick and rigid cross-sections – and the prominently situated coil connections make a contribution to rational wiring operations.


Monting

box terminal Contactor DILMP from 20 A to 200 A feature box terminals with two cable connection areas. Thus, different conductor cross-sections can be safely wired – even on machine subject to a high level of vibration. This simplifies wiring and reduces wiring errors.

Contactors with DC and AC mechanisms have identical geometry's. The performance of all mechanisms and the ratio of switched power to required auxiliary power is improved significantly.

 

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.
