Type A residual current circuit breaker, 3-phase + neutral, 40A 30 mA

ONESTO Residual Current Circuit Breaker, Type A, 4-pole, 40A, 30 mA

The ONESTO Type A Residual Current Circuit Breaker is used for detecting residual currents and disconnecting the protected circuit in the event of their occurrence. It responds to sinusoidal alternating residual currents as well as 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 30mA.

Technical Data:

• Type of device: Residual current circuit breaker without overcurrent protection - RCCB
• Type: A
• Number of poles: 4P
• Rated current In: 40A
• Rated residual current IΔn: 30mA
• Rated voltage according to the catalog: 415 V AC
• Rated frequency: 50/60 Hz
• Standards specified by the manufacturer: IEC/EN 61008-1, IEC/EN 61008-2-1

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