C137 – C165 series contactors are suitable for handling DC loads in the range of 40 A up to 220 A for the most common coil voltages up to 120 V. The contactors have double-break contacts, a compact design, and function most reliably.
Version “C” are single pole NO contactors with magnetic blowout, whereas version “H” are single pole changeover contactors fitted with an additional galvanically isolated NC contact. The switching devices can be used as main or auxiliary contactors.
