1SDA060733R1 ABB E3S-A 3200 PR121/P-LSIG 3200 A 3P Withdrawable Air Circuit Breaker

Why Choose the ABB E3S-A 3200 PR121/P-LSIG In=3200A 3p W?

The ABB E3S-A 3200 PR121/P-LSIG In=3200A 3p W, order code 1SDA060733R1, is a high-capacity SACE Emax E3S-A withdrawable air circuit breaker moving part designed for demanding industrial low-voltage power distribution. It combines a 3200 A rated current with ABB's electronic PR121/P-LSIG overcurrent release, providing comprehensive protection for main distribution and high-current feeder applications.

This circuit breaker uses a three-pole withdrawable configuration identified by ABB as a moving part (MP). It is designed to operate with the appropriate E3 fixed part, allowing the breaker to be racked out for inspection, servicing or replacement while the fixed portion remains installed in the switchboard.

The integrated PR121/P electronic release provides LSIG protection, combining long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. This UL E3S-A configuration also includes four auxiliary contacts and circuit-breaker open/closed position indication, providing a robust solution for high-current switchgear requiring comprehensive protection and serviceable withdrawable construction.

High-Current Withdrawable Protection for Industrial Switchgear

The ABB E3S-A platform combines the robust switching architecture of the SACE Emax family with electronic protection for demanding high-current distribution systems. As a withdrawable moving part, the 1SDA060733R1 is designed to interface with the appropriate fixed part, providing a serviceable circuit breaker arrangement that supports maintenance and replacement without permanently mounting the breaker body to the switchboard.

Its PR121/P-LSIG electronic release provides long-time, short-time, instantaneous and ground-fault protection against a broad range of overload and fault conditions. Combined with a 3200 A rated current, four auxiliary contacts and open/closed position indication, the breaker provides a comprehensive high-current protection solution for critical industrial distribution systems.
