Why Choose the ABB T7V1000 PR331/P-LSIG 1000A 3-Pole Circuit Breaker?
The ABB T7V1000 PR331/P-LSIG is a high-performance moulded case circuit breaker (MCCB) designed for reliable protection and switching in demanding low-voltage power distribution systems. As part of the proven ABB SACE Tmax T7 series, it combines a 1000 A rated current with the PR331/P electronic trip unit for comprehensive overcurrent and earth-fault protection.
The PR331/P-LSIG electronic release provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. These protection functions enable the breaker to respond to multiple electrical fault conditions while supporting effective coordination and selectivity throughout industrial and commercial distribution networks.
This model is supplied in an authoritative 3-pole fixed configuration. The T7V performance level is intended for installations with high prospective fault currents, making the T7V1000 suitable for main distribution boards, industrial switchboards and high-current three-phase feeders requiring advanced electronic protection.
