Description
Modular circuit breakers (MCB) VA47-60 are intended for automatic power source cut-off under excess currents. Recommended for use in group panels (apartment and floor) and distribution boards of residential, domestic, public and administrative buildings.
Advantages
- Two types of protection against overloads and short circuit.
- Complete set of supplementary devices with the possibility of simple independent installation:
- – State contact KS47;
- – State contact KSV47;
- – Undervoltage trip RMM47;
- – Low-voltage release RN47.
- Improved arc suppression system: extended service life, increased resistance to short-circuit currents.
- Contact position indicator.
- Wide operating temperature range from –40 to +50° С.
- Simultaneous connection by FORK bar and flexible conductor is possible for power supply distribution via upper terminals, as well as connection by PIN bar.
- New ergonomic design of ON/OFF lever.
- Notched terminal clamps reduce the heat loss and increase mechanical stability of the connection.
