ABB 1SDA071869R1

The E6.2H 4000 is an air circuit breaker designed for robust electrical protection, accommodating a rated current of 4000 A and a maximum operational voltage of 690 V AC. This model includes four auxiliary contacts and operates with a solid-state release system, specifically the Ekip Hi-Touch LSIG, ensuring reliable performance in demanding applications.

With an impressive electrical durability rated for 10,000 cycles at 440 V and 4000 cycles at voltages from 500 V to 690 V, this breaker supports 10 cycles per hour under specified conditions. Its mechanical durability extends to 12,000 cycles at a rate of 60 cycles per hour. The breaker maintains a power loss of 309 W during operation.

In terms of short-circuit performance, the rated service short-circuit breaking capacity can reach 100 kA across various voltage levels, ensuring comprehensive protection in case of fault conditions. The rated ultimate short-circuit breaking capacity (Icu) also sustains 100 kA for voltages up to 690 V AC.

This product conforms to IEC standards and includes a tight connection with a torque of 70 N·m. Its dimensions are 888 mm in width, 371 mm in height, and 270 mm in depth, weighing 125 kg. The Designation Code for this air circuit breaker is E6.2.
