hello DEEPSTR2010, Here the details of the two 3TF50 coils: Closing power consumption of DC-coil: 500W for max. 40ms Closing power consumption of AC-coil: 550VA for max. 50ms The operating range is 0,8...1,1 x Us Check this coil datawith your application! Please also check the stability of your control voltage. Unstable control voltage can be the result of
- an insufficiently sized control transformer - drop of the line voltage during closing If this answer will not help you, please contact mailto:technical-assistance@siemens.com kind regards LesPaul |
