1SDA059642R1 ABB E3H/E 3200 Special 1150 V AC Emax Circuit Breaker

Why Choose the ABB 1SDA059642R1 E3H/E 3200 Special 1150 V AC Version?

The ABB 1SDA059642R1 is a special SACE Emax E3H/E 3200 circuit-breaker execution designed for demanding low-voltage power distribution applications operating at 1150 V AC. As part of the ABB New Emax product range, this special version combines the E3 frame with H-level performance and a rated uninterrupted current of 3200 A.

Developed for installations requiring a higher operating voltage than standard low-voltage Emax configurations, the E3H/E 3200 special execution provides protection and switching for high-current industrial electrical systems. Its protection system offers adjustable overload and instantaneous short-circuit settings, allowing the circuit breaker to respond appropriately to abnormal current conditions while supporting reliable distribution-system operation.

With a rated voltage of 1150 V AC and a rated uninterrupted current of 3200 A, the 1SDA059642R1 is particularly suited to specialised industrial power networks. The unit incorporates a complete protection system, trip indication and push-button operation, while optional motor operation provides additional flexibility for switchgear and automation applications.

Specialised Protection for 1150 V AC Power Distribution

Special Emax executions such as the ABB E3H/E 3200 are intended for industrial electrical systems requiring operating characteristics beyond those of standard low-voltage circuit-breaker configurations. The 1150 V AC rating makes this version suitable for specialised power distribution networks where high operating voltage and substantial continuous current capability are required.

The adjustable overload range allows protection to be configured between 1280 A and 3200 A, while the instantaneous short-circuit release can be adjusted between 4800 A and 48000 A. These settings provide flexibility when coordinating the circuit breaker with conductors, equipment and other protective devices within a high-current industrial distribution system.

Typical Applications

• Specialised 1150 V AC industrial power distribution systems.
• High-current industrial switchboards and switchgear.
• Heavy manufacturing and process plants.
• Mining and mineral-processing electrical systems.
• Large machinery and production installations.
• High-capacity electrical distribution networks.
• Industrial installations requiring adjustable overload and short-circuit protection.
• Special-purpose ABB SACE Emax switchgear assemblies.
