ABB 1SDA071771R1

The E4.2N 3200 model is an air circuit breaker specifically engineered for fixed installations, accommodating a rated current of 3200 A. It operates with an electrical durability rating of Ue ≤ 440 V for up to 7000 cycles, and can sustain 20 cycles per hour, while also providing mechanical durability for up to 20,000 cycles at a frequency of 60 cycles per hour.

With a neutral pole current at 100%, this circuit breaker is equipped with four poles and incorporates a solid-state release type known as Ekip Dip LI, classified under the IEC standards. The rated voltage is set at 690 V AC, with a short-circuit breaking capacity (Ics) of 66 kA across multiple voltages up to 690 V AC. Additionally, it features a rated impulse withstand voltage of 12 kV according to IEC 60947-2.

Significant specifications include a power loss of 425 W and a rated uninterrupted current of 3200 A. The terminal connection is designed as rear flat horizontal with a bolt type, requiring a tightening torque of 70 N·m. This unit is classified as suitable for IT networks, further enhancing its application versatility.

This product not only meets environmental standards but also achieves a recyclability rate of 77.4% in alignment with EN45555, demonstrating a commitment to sustainable practices.
