Residual-current circuit breaker 2P Kanlux KRO6-2/B10/30 — 2-pole, B curve, 10 A, 30 mA, type AC

Kanlux KRO6-2/B10/30 is a 2-pole residual-current circuit breaker (RCBO) combining overcurrent protection and earth-leakage detection in a single compact device. Designed for domestic and light commercial electrical installations, this unit integrates a B-curve magnetic characteristic for reliable tripping on short circuits, a 10 A rated current for circuit protection and a 30 mA AC-type residual current trip to reduce risk of electric shock. The breaker fits standard DIN-rail switchgear and provides coordinated protection for circuits where both overload/short-circuit and residual-current protection are required.

Advantages

This residual-current circuit breaker delivers coordinated protection by combining thermal-magnetic overcurrent interruption with sensitive residual-current detection, simplifying distribution board layouts and reducing component count. The B-curve characteristic ensures prompt response to short-circuit currents typical of household and light commercial loads while maintaining stability during temporary inrush currents. With a 30 mA trip threshold of AC type, the device provides reliable detection of sinusoidal alternating earth-fault currents and helps prevent electric shock without affecting normal operation of most appliances.

Suitable for

• Protection of lighting and socket circuits in apartments and houses
• Sub-circuits in small offices and retail spaces
• Circuits requiring combined overcurrent and residual-current protection
• Retrofit or new installations on standard DIN-rail distribution boards

Key specifications

• Number of poles: 2 (two-pole protection)
• Tripping curve: B characteristic (thermal-magnetic)
• Rated current: 10 A
• Residual current sensitivity: 30 mA, type AC (sinusoidal alternating currents)
• Function: Combined overcurrent (short-circuit/overload) and residual-current protection (RCBO)
• Mounting: DIN-rail compatible, compact housing suitable for distribution boards

How to use

Install the RCBO on a standard DIN rail in the distribution board following local wiring regulations and ensuring power is isolated before work begins. Connect the line and neutral conductors to the designated terminals and ensure correct polarity. After installation, perform an insulation and continuity check of the circuit, then energise and test the residual-current function using an appropriate test procedure or test instrument. Verify that the device trips at the expected residual current level and that the manual toggle operates smoothly.

Usage recommendations

Use this device in circuits with compatible nominal current and expected load characteristics; avoid installing where DC residual currents or highly distorted waveforms are present unless additional measures are in place. Regularly test the residual-current trip function according to applicable standards and local regulations to ensure continued protection against electric shock.
