Why Choose the ABB T7L 1000 PR332/P LSIRc 1000A Circuit Breaker?
The ABB 1SDA062832R1, designated T7L 1000 PR332/P LSIRc In=1000A 4p F F M, is a high-performance four-pole moulded-case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the proven ABB Tmax T7 series, it combines a rated uninterrupted current of 1000 A with the advanced PR332/P LSIRc electronic trip unit for comprehensive overcurrent and residual-current protection.
The T7L version provides high short-circuit interruption performance, with a rated ultimate short-circuit breaking capacity of 120 kA at 380–415 V AC. Its PR332/P LSIRc electronic release provides adjustable long-time, short-time and instantaneous overcurrent protection together with residual-current protection, enabling effective protection of high-current industrial and commercial distribution networks.
With its four-pole configuration, fixed installation, front terminals and stored-energy operating mechanism, the 1SDA062832R1 is suitable for three-phase and neutral distribution systems requiring dependable protection and flexible switching. Its high breaking capacity and 690 V AC rated voltage make it particularly suitable for main switchboards, power distribution centres and industrial installations with substantial prospective fault currents.
