1SDA059292R1 ABB E2N 1000 PR123/P-LSIG 1000 A 4-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA059292R1 E2N 1000 Air Circuit Breaker?

The ABB 1SDA059292R1 is a high-performance SACE Emax E2N 1000 air circuit breaker designed for protection, switching and isolation in demanding low-voltage power distribution systems. Configured as E2N1000PR123/P-LSIG In=1000A 4p W, it combines a 1000 A rated current, four-pole construction and ABB's advanced PR123/P-LSIG electronic overcurrent release.

As part of the established ABB SACE Emax range, this circuit breaker provides comprehensive electronic protection for industrial and commercial electrical networks. The PR123/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection functions, helping safeguard conductors, busbars and connected equipment against overload, short-circuit and earth-fault conditions.

The 1SDA059292R1 is supplied as a four-pole withdrawable moving part (W/MP) for use with the corresponding Emax fixed part. The breaker is fitted with four auxiliary contacts and open/closed position indication, while its withdrawable construction supports convenient inspection, servicing and replacement in critical low-voltage switchboards.

Reliable Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax E2N protect high-current low-voltage distribution circuits while providing dependable switching and isolation. The PR123/P-LSIG electronic release combines overload, selective short-circuit, instantaneous short-circuit and ground-fault protection, supporting coordinated protection of switchboards, feeders and connected electrical equipment.

The withdrawable construction makes the 1SDA059292R1 particularly suitable for switchboards where maintainability and operational flexibility are priorities. When installed with the corresponding Emax fixed part, the breaker moving assembly can be withdrawn for inspection, testing or servicing while the permanent switchboard connections remain in place.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical distribution.
• Manufacturing and process plant switchgear.
• Protection of high-current feeders and distribution circuits.
• Four-pole distribution systems requiring ground-fault protection.
• Withdrawable switchgear requiring advanced LSIG electronic protection.
