Why Choose the ABB 1SDA055824R1 E2B2000 Air Circuit Breaker?
The ABB 1SDA055824R1 is a high-performance SACE Emax E2B2000 air circuit breaker (ACB) designed for dependable switching and protection in high-current low-voltage electrical distribution systems. Part of the ABB New Emax series, this three-pole fixed circuit breaker 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 while providing adjustable protection suitable for industrial, commercial and infrastructure distribution networks.
This E2B2000 configuration features a three-pole fixed construction with rear horizontal terminals. It is rated for operation up to 690 V AC and provides a rated ultimate short-circuit breaking capacity of 42 kA, with four auxiliary contacts and open/closed circuit-breaker position indication supporting integration into switchboard monitoring and control systems.
