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.
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.
OperationAll 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.
