1SDA060801R1 ABB E3H-A 800 PR122/P-LI 800 A 3P Withdrawable Air Circuit Breaker

Why Choose the ABB E3H-A 800 PR122/P-LI In=800A 3p W MP?

The ABB E3H-A 800 PR122/P-LI In=800A 3p W MP, order code 1SDA060801R1, is a high-performance SACE Emax E3H-A withdrawable air circuit breaker moving part designed for demanding industrial low-voltage power distribution. It combines an 800 A rated current with ABB's PR122/P-LI electronic overcurrent release, providing dependable overload and instantaneous short-circuit protection.

This circuit breaker features a three-pole withdrawable configuration, identified as a moving part (MP), for use with a compatible E3 fixed part. The withdrawable architecture allows the breaker to be racked out for inspection, maintenance or replacement while the fixed part remains installed within the switchboard, providing valuable serviceability for critical electrical distribution systems.

The E3H-A 08 frame provides a short-circuit current capability of 85 kA at 480 V AC and a short-time current capability of 65 kA. Together with its PR122/P electronic release, UL configuration, four auxiliary contacts and open/closed position indication, the 1SDA060801R1 provides a robust protection solution for industrial switchboards and high-fault-level distribution applications.
