Description
Power circuit breakers VA07-M are installed in the distribution devices of transformer substations, main and input switchboards as protection and control devices on the input and outgoing lines. Used to protect generators, transformers, buses, cables in industrial and civil construction.
VA07-M are used in electrical networks with rated operating voltage up to 690V and are designed for rated currents from 800 to 3200A. Maximum switching capacity - from 42 to 80 kA at a voltage of 400V.
Meet the requirements of GOST IEC 60947-1, 50030.2.
Basic equipment includes: - Combined electronic release with LSI protection and earth fault protection; - Electric drive; - Manual drive; - Coil inclusion; - Shunt release; - Minimum voltage release; - On cycle counter; - Horizontal leads.
Advantages
- Two types of overcurrent protection: thermal and electromagnetic.
- Independent contact position indicator.
- Can be snapped on to DIN-rail, with double locking.
- Wide operating temperature range from –40 to +50° С.
- Wide lever for convenient switching ON/OFF of the circuit breaker.
- Notches on the terminal clamps reduce the heat loss and increase mechanical strength of the connection.
