Why Choose the ABB E4V 3200 PR121/P-LSIG 3200A 3P Withdrawable Air Circuit Breaker?
The ABB 1SDA056898R1 is a high-performance SACE Emax E4V air circuit breaker moving part designed for protection and switching in high-current low-voltage electrical distribution systems. Rated at 3200 A, this three-pole breaker incorporates an ABB PR121/P-LSIG electronic overcurrent release providing long-time, short-time, instantaneous and earth-fault protection.
As part of the proven ABB SACE Emax series, the E4V 3200 is engineered for demanding industrial and commercial power distribution applications requiring high breaking capacity, selective protection and dependable circuit interruption. Its withdrawable execution allows the moving part to be disconnected from the associated fixed cradle for inspection, servicing or replacement while retaining the main switchboard connections.
This version is a three-pole withdrawable E4V breaker moving part with a rated uninterrupted current of 3200 A. The E4V frame provides an ultimate short-circuit breaking capacity of 150 kA at 415 V AC and a short-time withstand current of 100 kA for 1 s, making it suitable for installations with very high prospective fault currents.
Key Advantages
- High-current 3200 A SACE Emax air circuit breaker for demanding power distribution systems.
- Three-pole configuration for three-phase electrical networks.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E4V provide switching and overcurrent protection for major low-voltage distribution circuits. The electronic trip unit continuously monitors circuit conditions and initiates breaker operation when configured overload, short-circuit or earth-fault thresholds are exceeded.
The PR121/P-LSIG release combines four principal protection functions in one electronic unit. This allows the breaker to protect against sustained overloads, delayed and instantaneous short circuits and earth faults while supporting coordinated protection throughout industrial and commercial electrical distribution networks.
Typical Applications
- Main incoming circuit breakers in low-voltage switchboards.
- Industrial power distribution systems.
- High-current feeder protection.
- Commercial and infrastructure electrical distribution.
- Transformer secondary protection and switching.
- Manufacturing and process plants.
- Generator and utility distribution systems.
- Switchboards requiring withdrawable high-breaking-capacity circuit breakers.
