The E4.2S 3200 is a three-pole air circuit breaker equipped with a solid-state release (Ekip Dip LI) suitable for alternating current applications. It features a rated current of 3200 A and a rated operational voltage of 690 V AC. The electrical durability allows it to operate effectively under conditions up to 440 V for 7000 cycles and between 500 to 690 V for the same number of cycles, supporting 20 cycles per hour.

Mechanical durability is rated at 20,000 cycles with a capacity for 60 cycles per hour. The device delivers a power loss of 425 W and is compliant with IEC standards. With a rated short-circuit breaking capacity (Icu) of 85 kA for voltages up to 440 V and 66 kA for higher voltages, the breaker ensures reliable protection against short circuits. It has a rated insulation voltage (Ui) of 1000 V AC and a rated impulse withstand voltage (Uimp) of 12 kV according to IEC 60947-2.

The terminal connections are designed for a rear flat horizontal configuration and utilize bolt terminals, with a tightening torque of 70 N·m. This circuit breaker is classified under ETIM 9 as a power circuit-breaker for transformer and generator protection and is suitable for IT networks at 690V. The product also meets environmental standards, with a recyclability rate of 77.4% according to EN45555.
