-  Rated currents: 630 A to 6300 A with fixed-mounted or withdrawable version
- 3 sizes for different rated current ranges (see illustration "Overview of SENTRON WL circuit-breakers/non-automatic circuitbreakers")
- 3 and 4-pole versions
- Rated operational voltage up to AC 690 V and 1000 V. Special versions up to AC 1000 V available
- 3 different switching capacity classes in the range from 50 kA to 100 kA for AC applications and one switching capacity class for DC applications.

 

The SENTRON WL circuit-breakers are supplied complete with operating mechanism (manual operating mechanism with mechanical closing), electronic overcurrent trip unit and auxiliary switches (2 NO contacts + 2 NC contacts in the standard version), and can be equipped with auxiliary releases.

 

• As incoming-feeder, distribution, tie, and outgoing-feeder circuit-breakers in electrical installations.
• For switching and protecting motors, capacitors, generators, transformers, busbars and cables.
• Application as an EMERGENCY-STOP switch in conjunction with an EMERGENCY-STOP device (DIN VDE 0113, IEC 60 204-1).
- Due to the reinforced use of electronic control systems, the demands made on air circuit-breakers in terms of operator control and monitoring of network processes have increased.
- The extensive, coordinated SENTRON range of devices covers all applications between 16 A and 6300 A with compact and air circuit-breakers.
- The AC devices are available as circuit-breakers and non-automatic circuit-breakers. DC devices are only available as non-automatic circuit-breakers.
