ABB SACE EMAX E2S 800A 690V Icw 65kA/1s

The E2S is a withdrawable air circuit breaker from ABB classic SACE Emax series, rated continuous current 800A, rated operational voltage 690V AC, rated short-time withstand current Icw=65kA for 1 second. This E2S supports 3-pole or 4-pole configuration, available with PR121, PR122, PR123 electronic trip units, realizing LI, LSI or LSIG protection including overload, short-time delay, instantaneous short-circuit and earth fault protection. The S stands for high short-circuit performance grade.

This E2S 800A adopts spring stored-energy operating mechanism, supporting local manual operation and optional motor operator for remote closing and tripping. Withdrawable design has connected, test and isolated positions for safe maintenance without removing busbars. It can be fitted with auxiliary contacts, trip alarm switch and communication modules for Modbus, uploading measured values, fault records and breaker status to SCADA and energy management systems. It complies with IEC 60947-2 standard.

The E2S is widely used in industrial substations, power plants and large factory low voltage main switchboards. The classic Emax platform is discontinued by ABB and replaced by Emax 2 series. Most available E2S 800A units are tested surplus spare parts for legacy panel overhaul and emergency replacement.
