Why Choose the ABB E4V3200 PR121/P-LSIG 3200A Air Circuit Breaker?
The ABB E4V3200 PR121/P-LSIG, order code 1SDA056882R1, 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-LSIG R3200 electronic overcurrent release.
The PR121/P-LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. These LSIG functions provide comprehensive protection for switchboards, busbars, feeders, cables and connected equipment while supporting coordinated protection in high-capacity industrial and infrastructure electrical networks.
The 1SDA056882R1 is supplied as a three-pole fixed circuit breaker with rear horizontal terminals. Its E4V performance level is intended for installations with very high prospective fault currents, while the fixed construction and rear horizontal terminal arrangement support integration into high-capacity low-voltage switchboards.
