Why Choose the ABB E3H1600 PR122/P-LSI 1600A 3P Fixed Air Circuit Breaker?
The ABB E3H1600 PR122/P-LSI, order code 1SDA056404R1, is a high-performance 1600 A three-pole air circuit breaker from the ABB SACE Emax E3 series, designed for switching and protection in demanding low-voltage industrial and commercial power distribution systems. This E3H configuration combines fixed installation with the advanced PR122/P-LSI R1600 electronic overcurrent release for precise and dependable circuit protection.
The PR122/P-LSI electronic release provides long-time, short-time and instantaneous protection, helping protect cables, busbars, transformers and connected equipment against overload and short-circuit conditions. Compared with the basic PR121/P platform, the PR122/P trip unit provides enhanced protection, measurement and system-management capabilities for sophisticated distribution applications.
With a rated current of 1600 A, a three-pole configuration and fixed construction with rear horizontal terminals, the E3H1600 is suited to substantial distribution loads where high fault-clearing performance and selective protection are required. Four auxiliary contacts and circuit-breaker open/closed position indication support integration with switchboard control and signalling systems.
