Why Choose the ABB E4V 3200 PR121/P-LSI 3200A 3P Withdrawable Air Circuit Breaker?
The ABB 1SDA056897R1 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-LSI electronic overcurrent release for long-time, short-time and instantaneous protection.
As part of the proven ABB SACE Emax range, the E4V 3200 is engineered for demanding industrial and commercial power distribution applications where high current capacity, selective protection and dependable circuit interruption are required. The withdrawable execution allows the breaker moving part to be disconnected from its fixed cradle for inspection, servicing or replacement without dismantling the main power connections.
This version is a three-pole withdrawable E4V breaker moving part with a rated uninterrupted current of 3200 A. It is supplied with the PR121/P-LSI R3200 electronic trip unit, four auxiliary change-over contacts and circuit-breaker open/closed position indication, providing a comprehensive solution for protecting major distribution feeders and high-power installations.

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. By continuously monitoring current through the electronic trip unit, the breaker can disconnect the circuit when overload or short-circuit conditions exceed configured protection thresholds.
The PR121/P-LSI release combines long-time overload protection with short-time delayed and instantaneous short-circuit protection. This combination supports selective coordination within electrical distribution systems while helping protect cables, busbars, transformers and connected equipment from damaging overcurrents.
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.
- Motor control centres and major process installations.
- Generator and utility distribution systems.
- Power distribution panels requiring withdrawable circuit breakers.
