Product details

It protects a 1P+N circuit at 6 A rated current (at 30 °C) with a B-curve tripping characteristic, meaning it will trip at 3–5 times rated current for fast short-circuit response on resistive or light inductive loads.

Rated IP20 with conductors connected and distribution board installed. Ambient temperature range -40 °C to 75 °C, but the current must be derated above 30 °C — at 40 °C it carries 5.7 A, at 50 °C 5.4 A, at 60 °C 5.1 A, and at 70 °C 4.62 A. Halogen-free and silicon-free construction.

Coordination & compliance

Overvoltage category III, pollution degree 2, insulation voltage 264 V, surge voltage resistance 4 kV. Energy limitation class 3. The RCBO is instantaneous type (no intentional delay). For selectivity studies, the 25 kA rating under IEC 60947-2 gives better fault-clearing capability than the 6 kA EN 60898 rating — useful when coordinating with upstream breakers in a high-fault panel.

Frequently asked questions

What is the width and depth of this RCBO?

Width is 36 mm (2 modular units), depth is 77 mm (installation depth 70 mm).

What breaking capacity does it have?

6 kA per EN 60898 and 25 kA per IEC 60947-2.

What is the derated current at elevated ambient temperatures?

At 40 °C it carries 5.7 A, at 50 °C 5.4 A, at 60 °C 5.1 A, and at 70 °C 4.62 A.
