Residual current circuit breaker type A, 3-phase + neutral, 40A 100 mA

ONESTO Residual Current Circuit Breaker, Type A, 4-Pole, 40A, 100 mA

The ONESTO Type A Residual Current Breaker is designed to detect residual currents and disconnect the protected circuit in case they occur. It responds to sinusoidal alternating residual currents and pulsing direct residual currents.

The 4-pole design: three phases and a neutral wire is intended for use in three-phase circuits with a neutral wire. The rated current of the device is 40A, and the rated residual current is 100mA.

Technical specifications:

• Device type: residual current circuit breaker without overcurrent protection - RCCB
• Type: A
• Number of poles: 4P
• Rated current In: 40A
• Rated residual current IΔn: 100mA
• Rated voltage according to the catalog: 415 V AC
• Rated frequency: 50/60 Hz
• Standards indicated by the manufacturer: IEC/EN 61008-1, IEC/EN 61008-2-1

The breaker does not provide protection against overload and short circuits. It requires the use of appropriately selected overcurrent protection. The selection of the rated current and residual current should be adapted to the installation requirements.
