Why Choose the ABB T7L 1000 PR332/P LSIRc 1000A Circuit Breaker?
The ABB 1SDA062816R1, designated T7L 1000 PR332/P LSIRc In=1000A 4p F F, 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 solid-state trip unit provides adjustable long-time, short-time and instantaneous overcurrent protection together with residual-current protection, allowing the breaker to respond effectively to a wide range of electrical fault conditions.
With its four-pole configuration, fixed installation and front main-circuit terminals, the 1SDA062816R1 is suitable for three-phase and neutral distribution systems in industrial plants, commercial buildings, infrastructure and main low-voltage switchboards. Its 1000 A rating and high breaking capacity make it particularly well suited to installations with substantial load currents and prospective short-circuit levels.
