Type A residual current circuit breaker, single-phase + neutral, 25A 30 mA

ONESTO Residual Current Device, type A, 2-pole, 25 A, 30 mA

The ONESTO type A residual current device is designed to detect differential currents and disconnect the protected circuit in the event of their occurrence. It responds to sinusoidal alternating differential currents as well as pulsating direct differential currents.

The 2-pole design: phase and neutral wire is intended for use in single-phase circuits. The rated current of the device is 25 A, and the rated differential current is 30 mA.

Technical specifications:

• Device type: residual current device without overcurrent protection - RCCB
• Type: A
• Number of poles: 2P
• Rated current In: 25A
• Rated differential current IΔn: 30 mA
• Rated voltage according to the catalog: 240 V AC
• Rated frequency: 50/60 Hz
• Standards indicated by the manufacturer: IEC/EN 61008-1, IEC/EN 61008-2-1

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