Why Choose the ABB T7L 1250 PR332/P LI Moulded Case Circuit Breaker?
The ABB T7L 1250 PR332/P LI is a high-performance 3-pole moulded case circuit breaker (MCCB) designed for protection and control of high-current low-voltage power distribution systems. As part of the proven ABB Tmax T7 series, it combines a 1250 A rated uninterrupted current with electronic protection and high short-circuit breaking capability for demanding industrial and commercial installations.
Equipped with the PR332/P LI solid-state electronic trip unit, the T7L 1250 provides long-time overload and instantaneous short-circuit protection. Its adjustable protection settings allow the breaker to be coordinated with cables, switchgear and downstream equipment, helping provide dependable protection across high-current distribution networks.
With an ultimate short-circuit breaking capacity of 120 kA at 415 V AC, a 3-pole configuration and fixed mounting with front terminals, the T7L 1250 is engineered for main distribution, feeder and switchboard applications where reliable interruption of substantial prospective fault currents is required.
