1SDA056643R1 ABB E3V2000 PR122/P-LI 2000A 3P Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E3V2000 PR122/P-LI 2000A 3P Withdrawable Air Circuit Breaker Moving Part?

The ABB E3V2000 PR122/P-LI, order code 1SDA056643R1, is a high-performance SACE Emax air circuit breaker moving part designed for demanding low-voltage power distribution systems. This three-pole withdrawable E3V breaker moving part has a rated uninterrupted current of 2000 A and incorporates the PR122/P-LI R2000 electronic overcurrent release.

The PR122/P-LI release provides long-time and instantaneous overcurrent protection, helping safeguard conductors, switchboards and connected equipment against sustained overloads and severe short-circuit faults. Its instantaneous short-circuit release is adjustable from 3000–30000 A, providing high-current fault protection for demanding distribution applications.

This version is supplied as the withdrawable moving part of the SACE Emax E3V circuit-breaker system. It is fitted with four change-over auxiliary contacts and circuit-breaker open/closed position indication. With a rated uninterrupted current of 2000 A and an ultimate short-circuit breaking capacity of 130 kA at 400 V AC, 50 Hz, it provides robust protection with the servicing flexibility of withdrawable switchgear.

High-Performance LI Protection with Withdrawable Flexibility

The ABB SACE Emax E3V platform is designed for major low-voltage distribution systems where substantial continuous-current capacity and high short-circuit interruption performance are required. The 1SDA056643R1 combines a 2000 A current rating with 130 kA ultimate breaking capacity at 400 V AC, helping protect important switchboards, conductors and downstream electrical equipment against damaging fault currents.

Its PR122/P-LI R2000 electronic release combines long-time overload protection with instantaneous short-circuit protection. The withdrawable moving-part construction also enables the circuit breaker to be isolated and removed from a compatible fixed part for inspection, servicing or replacement, making it particularly suitable for critical installations where maintainability and continuity of operation are important considerations.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• Transformer secondary protection.
• Main incoming circuit-breaker applications.
• High-fault-level outgoing feeder protection.
• Withdrawable switchgear requiring maintainable high-current circuit protection.
