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

• Combined MCB + RCD in a 1P+N DIN rail element, saving space and wiring time.
• Magnetic + thermal trip for overload and short circuit protection at C10A.
• Curve C — withstands motor, transformer, and LED driver inrush currents.
• Type A residual current 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.
