Why Choose the ABB E4V3200 PR121/P-LSI 3200A Air Circuit Breaker?
The ABB E4V3200 PR121/P-LSI, order code 1SDA056881R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in demanding high-current low-voltage electrical distribution systems. Part of the ABB SACE Emax E4V series, this three-pole fixed circuit breaker combines a 3200 A rated uninterrupted current with the PR121/P-LSI R3200 electronic overcurrent release.
The PR121/P-LSI electronic trip unit provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. These LSI functions help protect switchboards, busbars, feeders, cables and connected equipment against sustained overloads and short-circuit faults while supporting coordinated protection in high-capacity electrical networks.
The 1SDA056881R1 is supplied as a three-pole fixed circuit breaker with rear horizontal terminals. Its E4V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, making it particularly suitable for installations where very high prospective fault currents must be safely interrupted.
