1SDA060737R1 ABB E3S-A 3200 PR122/P-LI 3200 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA060737R1 E3S-A 3200 Withdrawable Air Circuit Breaker?

The ABB 1SDA060737R1 is a high-performance SACE Emax E3S-A 3200 withdrawable air circuit breaker moving part designed for reliable switching and protection in demanding low-voltage power distribution systems. Identified by ABB as E3S-A 3200 PR122/P-LI In=3200A 3p W, this three-pole breaker combines a 3200 A rated current with the advanced ABB PR122/P electronic overcurrent release.

As part of the established ABB SACE Emax range, the E3S-A is engineered for high-current switchboards where dependable overload and short-circuit protection are essential. Its PR122/P-LI electronic trip unit provides long-time and instantaneous protection functions, helping protect electrical distribution circuits and connected equipment against sustained overloads and severe short-circuit conditions.

This version features a withdrawable moving-part construction, allowing the circuit breaker to be disconnected and removed from its compatible fixed part for inspection, maintenance or replacement. The three-pole E3S-A configuration uses an R3200 overcurrent release with an instantaneous release reference of 48000 A and is fitted with four auxiliary contacts and open/closed position indication.

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 and is particularly useful in industrial switchboards where maintainability and minimising disruption to the main switchgear assembly are important.

The PR122/P-LI electronic trip unit gives the ABB 1SDA060737R1 long-time and instantaneous protection functions for dependable overload and short-circuit protection. Combined with its 3200 A three-pole withdrawable construction and R3200 overcurrent release, the breaker provides a robust solution for substantial industrial, commercial and infrastructure 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 building distribution systems.
• Infrastructure and engineered low-voltage switchgear.
