1SDA055936R1 ABB E2N2000 PR121/P-LI 2000A 3-Pole Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E2N2000 PR121/P-LI 2000A 3-Pole Withdrawable Air Circuit Breaker?

The ABB 1SDA055936R1 is a SACE Emax E2N air circuit breaker (ACB) moving part designed for switching and protection in demanding low-voltage electrical distribution systems. Rated at 2000 A, this three-pole withdrawable circuit breaker moving part is equipped with the PR121/P-LI R2000 electronic overcurrent release for dependable overload and instantaneous short-circuit protection.

As part of the ABB SACE Emax / New Emax range, the E2N2000 combines high-current switching capability with electronic circuit protection for industrial and commercial power distribution. The PR121/P-LI release provides long-time and instantaneous protection functions, helping protect cables, busbars, transformers and connected electrical equipment against sustained overloads and severe short-circuit currents.

The E2N2000 PR121/P-LI is a three-pole withdrawable moving part with a rated current of 2000 A. The E2N frame provides a 65 kA performance class for demanding low-voltage distribution applications, while its draw-out construction allows the moving part to be removed from the corresponding fixed part for inspection, maintenance or replacement.

Reliable Draw-Out Circuit Protection for High-Current Distribution

Air circuit breakers such as the ABB E2N2000 provide switching, isolation and protection for high-current low-voltage distribution circuits. The three-pole arrangement is designed for three-phase applications, while the withdrawable architecture allows the breaker moving part to be disconnected and removed from its corresponding fixed part for inspection, servicing or replacement without permanently disturbing the switchboard's main connections.

The PR121/P-LI electronic release provides long-time protection against sustained overload conditions and instantaneous protection against severe short-circuit currents. Combined with the E2N frame's 65 kA performance class, the 1SDA055936R1 is suited to demanding industrial and commercial distribution systems where high-current protection and maintainable draw-out switchgear are required.

Typical Applications

• Industrial low-voltage switchboards and distribution panels.
• Three-phase high-current electrical distribution systems.
• Main incoming circuit protection.
• High-fault-level feeder protection.
• Withdrawable and draw-out switchgear assemblies.
• Busbar and bus-coupler applications.
• Transformer secondary distribution systems.
• Manufacturing, process, commercial and infrastructure installations.
