RCBO (Residual Current Breakers with Overcurrent Protection)

97 parts

RCBOs (residual current breakers with overcurrent protection) from Siemens, ABB and Schneider Electric combine earth leakage, overload and short-circuit protection in one DIN-rail device. The range covers 6 A to 40 A in 1+N, 2, 3 and 4 poles, mainly Siemens 5SU1 plus ABB DS201 and Schneider Electric Acti9 iDPN N Vigi. Stoklink ships worldwide from Turkey.

Guide

RCBO (Residual Current Breakers with Overcurrent Protection) buying guide

What's in this range

  • Siemens 5SU1 RCBOs in 2-pole 230 V and 4-pole 400 V versions.
  • ABB DS201 RCBOs in 1P+N, 30 mA and 300 mA.
  • Schneider Electric Acti9 iDPN N Vigi, iDPNa Vigi and iCV40 devices.
  • Three-pole and four-pole RCBOs.

How to choose

  • Rated current: match the cable and load, from 6 A to 40 A in this range.
  • Curve: B for long cable runs and resistive loads, C for general use with moderate inrush.
  • Sensitivity: 30 mA for socket circuits and personal protection.
  • Breaking capacity: the kA value must exceed the prospective fault current at the board.
  • Standard: IEC 61009-1, with RCD type AC or A for the load.
FAQ

RCBO (Residual Current Breakers with Overcurrent Protection) questions

Why use an RCBO instead of an RCCB plus MCB?

An RCBO protects each circuit individually, so a leakage fault trips only that circuit. It also saves space in the board.

Is the neutral switched on a 1P+N RCBO?

On 1P+N devices the neutral is typically switched, so the module isolates both conductors. Check the datasheet of the specific part.

What is the lead time for RCBOs?

It depends on distributor stock for each part number. Stoklink ships from Turkey, EXW, and confirms timing with the quote.
