1SDA060703R1 ABB E2N-A 800 PR122/P-LI 800 A 3P Fixed Air Circuit Breaker

Why Choose the ABB 1SDA060703R1 E2N-A 800 Air Circuit Breaker?

The ABB 1SDA060703R1 is a SACE Emax E2N-A 800 air circuit breaker designed for dependable protection and switching in demanding low-voltage power distribution systems. This three-pole fixed breaker combines an 800 A rated current with ABB's PR122/P-LI electronic overcurrent release, providing long-time and instantaneous protection functions.

Configured as a fixed three-pole breaker, the 1SDA060703R1 features rear horizontal terminals for integration into compatible switchboards and busbar systems. The E2N-A designation combines the E2 frame with ABB's N breaking-performance level and the UL-oriented Emax configuration, making the breaker suitable for appropriately engineered industrial and commercial distribution assemblies.

The fitted PR122/P-LI R800 trip unit provides electronic overload and instantaneous short-circuit protection, while the breaker is also equipped with four auxiliary contacts and open/closed position indication. This combination provides a robust circuit protection platform with useful status signalling for switchboard operation and monitoring.

PR122/P-LI Electronic Circuit Protection

The ABB PR122/P-LI electronic trip unit provides two fundamental protection functions for the electrical system. The L function provides long-time protection against sustained overload conditions, while the I function provides instantaneous intervention when a severe short-circuit current is detected.

This protection arrangement makes the 1SDA060703R1 particularly suitable where straightforward electronic overload and short-circuit protection is required without additional short-time or earth-fault functions. Combined with its 800 A rating, fixed construction and rear horizontal terminals, the E2N-A provides an integrated protection and switching solution for compatible low-voltage switchboards.

Typical Applications

• Main low-voltage power distribution switchboards.
• Industrial electrical distribution systems.
• Commercial building main distribution boards.
• Manufacturing and process plant switchgear.
• Transformer secondary protection and distribution.
• Generator distribution systems where the breaker characteristics match the system design.
• Main incomer and feeder circuit-breaker applications.
• Fixed switchgear assemblies requiring electronic overload and instantaneous short-circuit protection.
