Why Choose the ABB E2H-A 1200 PR122/P-LSI 1200A 3P Withdrawable Air Circuit Breaker?
The ABB E2H-A 1200 PR122/P-LSI, order code 1SDA061125R1, is a high-performance SACE Emax air circuit breaker moving part designed for demanding low-voltage power-distribution systems. Rated at 1200 A, this three-pole E2H-A configuration combines robust current-handling capability with ABB's PR122/P-LSI electronic overcurrent release.
This specific breaker is a withdrawable moving part (W MP) for use with the corresponding SACE Emax fixed part. It incorporates an R1200 rating plug and an instantaneous protection reference of 18,000 A. The PR122/P-LSI release provides long-time, short-time and instantaneous protection functions for comprehensive LSI protection against overload and short-circuit conditions.
The E2H-A performance level is engineered for applications requiring robust short-circuit performance, while the withdrawable architecture provides additional serviceability for critical switchboards. The combination of a 1200 A rating, three-pole construction and electronic LSI protection makes the 1SDA061125R1 suitable for main incomers, high-current feeders and industrial power-distribution systems.

Reliable Protection for High-Current Power Distribution
The ABB SACE Emax E2H-A protects low-voltage electrical networks by monitoring current and interrupting the circuit when configured protection thresholds are exceeded. The PR122/P-LSI electronic release combines long-time overload protection with short-time and instantaneous short-circuit protection, helping safeguard cables, busbars, switchgear and connected equipment.
The withdrawable architecture allows the circuit breaker moving part to be isolated and removed from its compatible fixed part for inspection, servicing or replacement. Combined with its 1200 A current rating and electronic LSI protection, this makes the 1SDA061125R1 particularly suitable for maintainable industrial and commercial power-distribution switchboards.
Typical Applications
- Industrial low-voltage main distribution switchboards.
- Main incoming supply protection.
- High-current feeder and distribution circuit protection.
- Manufacturing and process-industry electrical systems.
- Commercial and infrastructure power distribution.
- Critical switchgear requiring serviceable withdrawable circuit breakers.
