Why Choose the ABB T7L 800 1SDA062676R1 Circuit Breaker?
The ABB 1SDA062676R1 is a high-performance Tmax T7L 800 moulded-case circuit breaker designed for protection and control of demanding low-voltage power distribution systems. Rated at 800 A, this three-pole circuit breaker combines a fixed mounting arrangement, front terminals and an advanced PR331/P LSIG electronic trip unit for comprehensive overload, short-circuit and earth-fault protection.
As part of the ABB SACE Tmax T7 range, the T7L 800 is engineered for industrial and commercial installations requiring high breaking capacity and flexible electronic protection. The L performance level provides a rated ultimate short-circuit breaking capacity of up to 120 kA at 415 V AC, making this breaker suitable for distribution systems with high prospective fault currents.
The PR331/P LSIG electronic trip unit provides long-time overload protection, selective short-time protection, instantaneous short-circuit protection and earth-fault protection. With an 800 A rated current, three-pole construction and fixed front-terminal configuration, the 1SDA062676R1 is well suited to main distribution boards, industrial switchboards and high-current power distribution applications.
