Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E2N2000 provide switching and protection for high-current low-voltage distribution circuits. Electronic trip technology enables abnormal current conditions to be detected accurately, allowing the breaker to disconnect the protected circuit according to configured protection parameters and helping safeguard cables, switchgear and connected equipment.

The PR122/P-LSI release provides L, S and I protection functions, covering long-time overload, short-time short-circuit and instantaneous short-circuit protection. Combined with the withdrawable SACE Emax architecture and four-pole construction, this configuration is well suited to switchboards requiring dependable high-current protection, selective coordination, maintainability and operational flexibility.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical distribution.
• Manufacturing and process plant switchgear.
• Incoming and outgoing high-current feeder protection.
• Four-pole distribution systems requiring withdrawable air circuit breakers.
