1SDA060731R1 ABB E3S-A 3200 PR121/P-LSIG 3200 A 3P Fixed Air Circuit Breaker

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

The ABB E3S-A 3200 PR121/P-LSIG In=3200A 3p F, order code 1SDA060731R1, is a high-capacity SACE Emax E3S-A fixed air circuit breaker engineered for demanding industrial low-voltage power distribution. It combines a 3200 A rated current with ABB's electronic PR121/P-LSIG trip unit, providing comprehensive protection for main distribution and high-current feeder applications.

This circuit breaker uses a three-pole fixed configuration with a specialised VR-HR rear terminal arrangement, comprising vertical rear and horizontal rear connections. The E3S-A platform provides an interrupting rating of 65 kA at 480 V AC, making it suitable for switchgear installations with substantial prospective fault currents.

The integrated PR121/P electronic release provides LSIG protection, combining long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. The 1SDA060731R1 is a UL configuration designed for high-current switchboards where dependable fault interruption, electronic protection and robust fixed installation are required.
