The REDLED Onesto KRCS2pro is a combined RCBO, a DIN rail device that integrates a miniature circuit breaker for short circuit and overload protection, along with a residual current device for earth leakage protection. A slim 1P+N unit replaces two separate components, saving space in the panel and simplifying wiring.

This model is designed for continuous load C25A with a type C curve, suitable for general-purpose circuits with moderate inrush currents such as lighting and small apartment sockets, kitchen circuits, or external socket power supply. The residual current side trips at 30 mA within less than 30 ms, providing electric shock protection, and is Type A, correctly detecting pulsating DC fault currents from modern electronics such as washing machines, EV chargers, and LED drivers.

• Combined MCB + RCD in one 1P+N DIN rail unit — saves space and wiring time.
• Magnetic + thermal trip for overload and short circuit protection at C25A.
• Type C curve — handles inrush currents of motors, transformers, and LED drivers.
• Type A leakage detection — responds to AC and pulsating DC fault currents.
• Leakage trip threshold 30 mA — life protection level according to IEC 61009.
• Short-circuit breaking capacity 6 kA — suitable for residential and light commercial panels.
• Test button on the front for monthly verification — recommended electrical safety practice.
