Why Choose the ABB 1SDA062931R1 T7L 1250 Circuit Breaker?
The ABB 1SDA062931R1, extended product type T7L 1250 PR232/P LSI In=1250A 3p F, is a high-performance moulded case circuit breaker (MCCB) designed for protection and switching in high-current low-voltage electrical distribution systems. As part of the established ABB SACE Tmax T7 series, it combines a 1250 A rated current with a PR232/P-LSI electronic trip unit for comprehensive overload and short-circuit protection.
The PR232/P-LSI electronic release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. These electronic protection functions allow the breaker characteristics to be configured to suit the electrical installation, helping provide effective coordination and dependable protection for conductors, switchgear and connected equipment.
With a rated uninterrupted current of 1250 A and a high short-circuit breaking capability, the T7L 1250 is engineered for demanding industrial and commercial power distribution. Its three-pole construction and fixed installation format make it particularly suitable for main distribution boards, industrial switchboards and other high-current low-voltage assemblies.
