MCCBs – Electronic MCCBs (AC)
Moulded Case Circuit Breakers Ex9M SU20L
- Version with parameter setting via DIP switches
- SU20L basic intelligent unit
- Frame sizes M2-M6
- Rated operating current up to 1600 A
- 3 and 4-pole versions
- Rated ultimate short-circuit breaking capacity Icu = Ics up to 150 kA
- Rated voltage 415 / 690 V AC
- High tripping accuracy, reliable operation, lower sensitivity to ambient temperature
Ex9M moulded case circuit breakers with SU20L type intelligent units are primarily designed for power distribution applications. Tests performed according to IEC / EN 60947-2 standards ensure functionality and reliability for a wide range of applications, including the isolation function. The electronic controller with DIP switches allows for quick and easy commissioning of the device based on system requirements. Electronic technology improves device stability in applications subject to significant mechanical stress. These circuit breakers are available with breaking capacities from 36 kA up to a maximum of 150 kA. The rated impulse withstand voltage Uimp up to 12 kV allows their use even in systems subject to high-intensity transient overvoltages, such as in heavy industry. Utilization categories A and B.
