Why Choose the ABB 1SDA055840R1 E2B2000 Air Circuit Breaker Moving Part?
The ABB 1SDA055840R1 is a high-performance SACE Emax E2B2000 air circuit breaker (ACB) moving part designed for dependable switching and protection in high-current low-voltage electrical distribution systems. Part of the ABB New Emax series, this three-pole withdrawable breaker moving part combines a rated uninterrupted current of 2000 A with the PR121/P-LI R2000 electronic overcurrent release.
The PR121/P-LI trip unit provides long-time (L) overload and instantaneous (I) short-circuit protection. These electronic protection functions help safeguard conductors, switchgear and connected equipment against damaging overcurrent conditions, providing dependable protection for industrial, commercial and infrastructure power distribution networks.
The 1SDA055840R1 is configured as the moving part of a three-pole withdrawable E2B2000 circuit breaker. Its withdrawable construction allows the breaker to be isolated and removed from its compatible fixed part for inspection, servicing or replacement, making it particularly suitable for critical installations where maintainability and continuity of electrical distribution are important.
