01.02 Residual Current Circuit Breakers

01.02.01 Residual current circuit breakers VD

01.02.01 Residual current circuit breakers VD

Residual Current Circuit Breaker (RCCB) VD1 is a quick-work safety breaker with response to residual currents without integrated overcurrent protection. Designed to protect a person from electric shock when accidentally inadvertently touching live parts of electrical installations and prevents the occurrence of fires due to leakage currents to the ground. It does not have its own energy consumption and has high mechanical wear resistance.
01.02.02 Residual current operated circuit breakers with integral overload protection AD12_14

01.02.02 Residual current operated circuit breakers with integral overload protection AD12_14

Residual Current Circuit Breakers with Overload protection (RCBO) AD12 and AD14 are a quick-acting protection circuit breakers ensure: – versions with tripping settings 10, 30 and 100mA: protection of persons against electric shock in case of unintentional direct contact with live parts of electric equipment; – versions with tripping setting 300mA: protection against fire caused by ignition of live parts insulation; – protection against overload and short-circuit; – protection against inadmissibly increased mains voltage (AD12M). The devices have indication of tripping caused by differential current, and AD12M also has LED indicator of ON status. The AD12M maintains operability when mains voltage drops to 50V. The devices use VA47-29 circuit breakers as commutation assemblies.
01.02.03 Residual current operated circuit breakers with integral overload protection AVDT

01.02.03 Residual current operated circuit breakers with integral overload protection AVDT

Residual Current Circuit Breakers with Overload protection (RCBO) AVDT32 are designed for protection of persons against electric shock in case of damaged insulation in electric installations, preventing fires caused by earth leakage currents and protection against overloads and short-circuits.
