B10N 2P ARMAT IEK residual current circuit breakers are independent of mains voltage and will continue to operate even in case of neutral loss. Functions of protection against overload currents and short-circuit, as well as arc chute in each pole.

Connection with PIN and FORK busbars is implemented top and bottom of the device. B10N RCCB allows connecting any additional ARMAT AUX series modular devices.

Advantages of electromechanical B10N 2P ARMAT IEK RCCBs

• Rated ultimate breaking capacity 10 kA guarantees safe device operation even at high short-circuit currents.
• Arc chute of 14 ferromagnetic plates increases resistance to multiple short-circuits.
• Maximum screw terminal tightening torque 5 N·m increases device energy efficiency and reduces overall heating of the RCCB.
• Independent mechanism of free release ensures safe switching.
• Protective output shutter prevents incorrect connection and error during conductor installation.
• Contact position indicator allows determining contact group state on/off at any time.
