Advanced Electronic Protection for Low-Voltage Distribution

Air circuit breakers are used to protect and control high-current low-voltage distribution circuits, interrupting overload and short-circuit faults while providing a means of circuit switching and isolation. The fixed E1B configuration provides a durable installation for switchboards where the circuit breaker remains permanently connected through its rear horizontal terminals.

The PR122/P-LSI electronic overcurrent release fitted to the ABB 1SDA059187R1 provides long-time protection against sustained overloads, short-time protection for selected short-circuit conditions and instantaneous protection against severe faults. Combined with its 1000 A rating, four-pole configuration and auxiliary position contacts, the breaker provides comprehensive protection and status indication for demanding electrical distribution applications.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• High-current feeder protection.
• Transformer and installation protection.
• Manufacturing and process plant switchgear.
• Commercial building electrical distribution.
• Infrastructure and utility distribution assemblies.
• Fixed low-voltage switchgear installations.
