1SDA060825R1 ABB E3H-A 3200 PR121/P-LSI 3200 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA060825R1 E3H-A 3200 Withdrawable Air Circuit Breaker?

The ABB 1SDA060825R1 is a SACE Emax E3H-A 3200 withdrawable air circuit breaker moving part designed for switching and protection in demanding low-voltage power distribution systems. Its full designation is E3H-A 3200 PR121/P-LSI In=3200A 3p W MP, combining a 3200 A rated current with the ABB PR121/P electronic overcurrent release.

As part of the ABB SACE Emax range, this E3H-A breaker is engineered for high-current switchboards requiring dependable overload and short-circuit protection. The PR121/P-LSI electronic trip unit provides long-time, short-time and instantaneous protection functions, supporting coordinated protection of electrical distribution circuits, switchgear and connected equipment.

This version has a three-pole withdrawable moving-part construction for use with a compatible Emax E3 fixed part. It incorporates an R3200 overcurrent release, a 48000 A instantaneous release reference, four auxiliary contacts and open/closed circuit-breaker position indication, while its withdrawable architecture supports efficient inspection, maintenance and replacement.

Advanced Withdrawable Protection for High-Current Distribution

Withdrawable air circuit breakers provide switching and protection while allowing the breaker moving part to be separated from its stationary fixed part. This architecture simplifies inspection, servicing and replacement because the breaker can be removed without dismantling the main switchboard power connections associated with the fixed part.

The PR121/P-LSI electronic trip unit gives the ABB 1SDA060825R1 long-time, short-time and instantaneous protection functions for coordinated overload and short-circuit protection. Combined with its 3200 A three-pole withdrawable construction, UL 1066 compliance and 85 kA interrupting rating at 480 V AC, it provides a robust solution for demanding high-current low-voltage distribution systems.

Typical Applications

• High-current industrial low-voltage switchboards.
• Main electrical power distribution systems.
• Withdrawable air circuit-breaker installations.
• Manufacturing and process plants.
• Large commercial and infrastructure power distribution systems.
• Engineered UL low-voltage switchgear assemblies.
