Why Choose the ABB T7V 1000 1SDA062857R1 Circuit Breaker?
The ABB 1SDA062857R1, specified here as T7V 1000 PR231/P I In=1000A 4p F F, is a high-performance SACE Tmax T7 moulded case circuit breaker (MCCB) designed for demanding low-voltage power distribution applications. It combines a 1000 A rated current with a PR231/P-I electronic trip unit and a four-pole fixed configuration with front terminals.
The T7V performance level is designed for installations with high prospective short-circuit currents, providing an ultimate short-circuit breaking capacity of 150 kA at 380–415 V AC. The PR231/P-I electronic trip unit provides adjustable instantaneous short-circuit protection, enabling rapid interruption of severe fault currents in high-current distribution systems.
With its four-pole construction, fixed installation and front-terminal arrangement, this configuration is suited to three-phase four-wire distribution systems where all four conductors are switched by the circuit breaker. Its combination of a 1000 A current rating, high breaking performance and electronic instantaneous protection makes it suitable for industrial switchboards, main distribution assemblies and high-current feeder protection.
