Free release mechanism with instantaneous switching - reduces the negative impact of the electric arc when turned on due to the stability of the contact closure speed

Arc removal copper-plated ferromagnetic clamp - forms the trajectory of the arc into the de-ionic grid, which accelerates arc extinction and reduces the thermal effect of the arc on the switching contacts

Arc-extinguishing cocoon - to effectively interrupt short-circuit currents, the switching contacts are placed in a ferromagnetic arc-extinguishing cocoon with linings made of insulating material

Soldering of contact parts on the movable and fixed contacts increases the arc-resistant properties of the contact system at the moment of switching off overcurrents

Increased connection capacity of leads - up to 50 mm2

Contact group position indicator - facilitates visual diagnosis of the on/off position of the contact group

Two arc extinguishing chambers with 24 plates in total increase the voltage drop across the electric arc at the moment of switching off short circuit currents and accelerate arc extinguishing

Increased strength of the case - 8 aluminum rivets connect the parts of the case, for strength and reliability of the structure, even when the maximum short circuit currents are turned off

Connect up to 4 additional AUX series devices - the device design allows you to connect up to 4 additional AUX series devices simultaneously

Additional insulating casing - the arc-extinguishing chamber is separated by a protective casing, in order to increase the insulating properties; it contains a channel necessary for the removal of gases at the moment of switching off short-circuit currents

Nominal terminal tightening torque 5 Nm - the circuit breaker design provides a nominal screw terminal tightening torque of 5 Nm. This reduces the contact resistance at the pin and increases the energy efficiency of the device.
