1SDA056827R1 ABB E4H3200 PR122/P-LI 3200 A 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E4H3200 PR122/P-LI Air Circuit Breaker?

The ABB E4H3200 PR122/P-LI, order code 1SDA056827R1, is a high-performance SACE Emax air circuit breaker designed for switching and overcurrent protection in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax E4 series, this four-pole fixed circuit breaker combines a 3200 A rated current with the PR122/P-LI R3200 electronic overcurrent release.

The PR122/P-LI release provides long-time overload and instantaneous short-circuit protection. These LI protection functions help safeguard conductors, busbars, switchboards and connected equipment against sustained overload conditions and severe short-circuit faults in high-capacity industrial and infrastructure electrical networks.

This configuration is a four-pole fixed circuit breaker equipped with rear horizontal terminals. Its E4H performance level is intended for installations with substantial prospective fault currents, while four auxiliary contacts and circuit-breaker open/closed indication support integration with switchboard signalling, monitoring and control systems.

Reliable LI Protection for High-Current Power Distribution

The ABB SACE Emax E4H3200 is designed for switching and protection at main incomer and high-current feeder levels within substantial low-voltage distribution systems. Its PR122/P-LI electronic release provides long-time protection against sustained overloads together with instantaneous intervention against severe short-circuit currents, helping protect switchboards, conductors and connected electrical equipment.

The combination of a 3200 A current rating, four-pole construction and E4H high-performance frame makes the 1SDA056827R1 particularly suitable for installations where substantial load currents and high prospective fault levels must be managed. Its fixed construction and rear horizontal terminals provide permanent switchboard integration, while auxiliary contacts enable breaker status to be incorporated into associated monitoring and control systems.

Typical Applications

• Main low-voltage distribution switchboards.
• High-current industrial power-distribution systems.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• Transformer secondary and main incomer protection.
• High-current feeder protection.
• Fixed power-distribution and switchgear assemblies.
