1SDA056616R1 ABB E3V1600 PR121/P-LI 1600A 4P Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E3V1600 PR121/P-LI 1600A 4P W MP Air Circuit Breaker?

The ABB E3V1600 PR121/P-LI, order code 1SDA056616R1, is a high-performance SACE Emax air circuit breaker moving part designed for switching and protection in demanding low-voltage power distribution systems. This E3 V configuration combines a 1600 A rated current, four-pole construction and a PR121/P-LI R1600 electronic overcurrent release.

Supplied as a withdrawable moving part (W MP), the E3V1600 is designed for use with a compatible E3 withdrawable fixed part. The draw-out arrangement enables the breaker to be isolated and withdrawn for inspection, servicing or replacement, making it particularly suitable for switchboards where maintainability and operational flexibility are important.

The PR121/P-LI electronic release provides long-time and instantaneous overcurrent protection, helping protect high-current distribution circuits against sustained overloads and severe short-circuit faults. The moving part is also fitted with four auxiliary contacts and open/closed position indication for integration with switchboard signalling, monitoring and control systems.
