DETAILED DESCRIPTION

These RCBOs provide protection in the case of both residual current and either short circuit or overcurrent detection. From a practical point of view, RCBOs integrate both functions of MCB and of RCCB.

They have a C-type (Curve) trip characteristic (instantaneous trip 5-10 times In) and are used for inductive loads (mixed loads, resistive and inductive with low inrush current).
In addition, they have a rated residual current (IΔn) of either 30mA or 300mA and are available with two different versions of residual current tripping type AC or A.

Type AC – Tripping for earth/ground fault is ensured “for residual sinusoidal alternating currents, suddenly applied or slowly rising”.

Type A – Tripping for earth/ground fault is ensured “for residual sinusoidal alternating currents and pulsating direct currents, suddenly applied or slowly rising”. In addition to the protection given by Type AC, this version protects against residual current with pulsating waveform. This can be caused by circuits connected with electronic equipment.

Certifications obtained: TÜV – Rheinland.
Compliant with standards: IEC/EN 61009-1.
