Reliable Power Distribution for Modular Circuit Protection
Busbars provide an efficient method of distributing an incoming electrical supply across groups of modular protection devices. By replacing multiple individual jumper wires with a purpose-designed conductive assembly, they can reduce wiring effort, improve panel organisation and provide consistent connections between compatible devices.
The ABB BF2-S9 DOWN 3N/12 is specifically designed for installations combining compatible S200 and SN201 miniature circuit breakers with F200 residual current devices. Its four-phase construction incorporates three phases and neutral, making it particularly useful in structured low-voltage distribution systems requiring coordinated MCB and RCD connections.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB S200 and SN201 miniature circuit breaker installations.
- ABB F200 residual current device installations.
- Three-phase and neutral distribution systems.
- Industrial control and automation panels.
- Commercial electrical switchboards.
