Why Choose the ABB T7V 1250 PR332/P LSI 1250A Circuit Breaker?
The ABB 1SDA062982R1, designated T7V 1250 PR332/P LSI In=1250A 3p F F M, is a high-performance three-pole moulded-case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the established ABB SACE Tmax T7 series, it combines a rated uninterrupted current of 1250 A with the PR332/P LSI electronic trip unit for configurable overload and short-circuit protection.
The T7V performance level provides very high short-circuit interruption capability, with an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC. The PR332/P LSI electronic release provides long-time, short-time and instantaneous protection functions, enabling effective protection of high-current circuits against sustained overloads and severe short-circuit conditions.
With its three-pole configuration, fixed construction, front terminals and stored-energy operating mechanism, the 1SDA062982R1 is designed for integration into professional low-voltage switchboards and power distribution assemblies. Its combination of 1250 A current capability, advanced electronic protection and high breaking capacity makes it particularly suitable for industrial, commercial and infrastructure installations with substantial prospective fault currents.
