C195 Series
Compact single pole contactors for voltages up to 1,200 V
Being of compact size and featuring double-break contacts that are covered for the most part, the C195 Series contactors provide high-performance current breaking. Their high contact force improves electrical performance and reliability even under harsh ambient conditions.
C195 versions with permanent-magnetic blowout are available for DC operation and without blowout magnets for AC operation respectively.
There is also the option of a SPDT version of the C195 which has an added galvanically isolated NC contact. Note: The added NC contact has a reduced current rating (I th) as compared to the contactor‘s NO contact.
The coils of the contactors come fitted as standard with varistors or TransZorb diodes for limiting overvoltages.
Features
- Suitable for years of continuous duty
