1SDA056628R1 ABB E3V2000 PR122/P-LSI 2000A 3P Fixed Air Circuit Breaker

Why Choose the ABB E3V2000 PR122/P-LSI 2000A 3P Fixed Air Circuit Breaker?

The ABB E3V2000 PR122/P-LSI, order code 1SDA056628R1, is a high-performance SACE Emax air circuit breaker designed for protection and switching in demanding low-voltage power distribution systems. This three-pole fixed E3V breaker has a rated uninterrupted current of 2000 A and incorporates the PR122/P-LSI R2000 electronic overcurrent release.

The PR122/P-LSI release provides long-time, short-time and instantaneous overcurrent protection. Its long-time function protects against sustained overloads, the short-time function supports selective short-circuit protection, and the instantaneous function provides rapid response to severe faults. The protection ranges include an overload setting of 800–2000 A and an instantaneous short-circuit setting of 3000–30000 A.

This version features a fixed three-pole construction with rear horizontal terminals and is supplied with four change-over auxiliary contacts plus circuit-breaker open/closed indication. With a rated voltage of 690 V and an ultimate short-circuit breaking capacity of 130 kA at 400 V AC, 50 Hz, the E3V2000 is suited to critical industrial, commercial and infrastructure distribution systems.

Advanced LSI Protection for High-Current Distribution

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. With a 2000 A current rating and 130 kA ultimate breaking capacity at 400 V AC, the 1SDA056628R1 provides robust protection for important switchboards, conductors and downstream electrical equipment.

Its PR122/P-LSI R2000 electronic release adds short-time protection to the long-time and instantaneous functions, allowing greater flexibility when coordinating upstream and downstream protective devices. Combined with the fixed rear-horizontal-terminal construction and auxiliary status contacts, this makes the breaker well suited to permanent switchboard installations where high fault performance, selectivity and reliable system monitoring are priorities.

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.
• Power distribution centres and fixed switchgear assemblies.
