C137, C163, C164, C165 – Battery contactors for railway, industrial and UPS applications
Unidirectional single pole NO or changeover contactors or with magnetic blowout
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.
Features
- Compact design
- Double-break contacts
- Easy to replace main contacts
- Blowout magnets
- Standards IEC 60947, EN 50124, IEC 60077-1
- 2 coil versions:
- for operation with charger switched off
- for operation with or without charger
Special variant
- Presented on this site are only stock items which can be supplied in short delivery time. Types for AC operation are available on special order: Replace version C with B (= NO contactor without blowouts) and version H with G (= changeover contactor without blowouts.
- If you need a special variant feel free to contact us. Maybe the type of contactor you are looking for is among our many special designs. If not, we can also supply customized designs. In this case, however, minumum order quantities apply.
