RP-Onesto - RCBO KRCS2pro Miniature circuit breaker 1P+N C10A 6kA Type A 30mA With Overload Protection

The REDLED Onesto KRCS2pro is a combined RCBO — a single DIN-rail module that integrates both a miniature circuit breaker for short-circuit and overload protection and a residual-current device for earth-leakage protection. One slim 1P+N unit replaces two separate components, saving space in your electrical panel and removing the wiring complexity of cascading an MCB and an RCD.

This model is rated for C10A continuous load on a Curve C characteristic — the right choice for general-purpose circuits with moderate inrush such as lighting + sockets in a small apartment, a kitchen circuit, or an outdoor socket feed. The residual-current side trips at 30 mA in less than 30 ms — fast enough to protect against electric shock — and is Type A, meaning it responds correctly to pulsating-DC fault currents from modern electronics such as washing machines, EV chargers and LED drivers.

Key Features

• Combined MCB + RCD in a single 1P+N DIN-rail module — saves space and wiring time
• Magnetic + thermal trip for overload and short-circuit protection at C10A
• Curve C characteristic — handles inductive inrush of motors, transformers and LED drivers
• Type A residual-current detection — responds to AC and pulsating-DC fault currents
• 30 mA leakage trip threshold — life-protection grade per IEC 61009
• 6 kA short-circuit interrupting capacity — suited to residential and light-commercial panels
• Test button on the front face for monthly verification — recommended electrical-safety practice
