Schneider Electric Resi9 R9F24120 Miniature Circuit Breaker 1P 20A C Curve 6kA

The Schneider Electric Resi9 R9F24120 is a high-performance miniature circuit breaker (MCB) designed for residential and commercial electrical installations. With a single pole, 20A rated current, and C tripping curve, it provides reliable overcurrent protection for lighting and general-purpose circuits. Its compact design and 6kA breaking capacity ensure safety and compliance with international standards.

Advantages

This MCB offers robust protection against overloads and short circuits, with a breaking capacity of 6kA at 230V AC. The C curve is ideal for circuits with moderate inrush currents, such as lighting and small motors. Easy DIN rail mounting and tunnel terminals simplify installation, while IP20 protection ensures safe operation in dry indoor environments.
