Description
Optical crosses are designed for switching the optical signals either from trunk lines or for distributing these signals over small server and office optical networks. They can be wall mounted or 19” version.
Advantages
- Compact design of the circuit breaker controlled by differential current, with built-in overcurrent protection.
- Rated conditional short-circuit current 6000 A allows for use of AVDT34 RCCBs as input protection devices.
- Wide range of rated currents (6, 10, 16, 20, 25, 32, 40, 50, 63 А) and rated tripping differential currents (10, 30, 100, 300 mA).
- Good electric wear resistance: at least 6000 switching operations.
- Ergonomic TEST button to check the device operability and correct connections.
- The work curve A at presence of differential current ensures a universal protection against electric shock in case of unintentional contact with conductor and protection against leakage currents.
- Design of the main contacts of 4-pole AVDT34 RCCB provides for early make and delayed break of neutral contact, thus preventing voltage unbalance in the load as in case of broken mains neutral.
