MCB 20A, 2P, 415V AC – 5SL4220-7RC

Product Description

Siemens SENTRON MCB 20A, 2P, 415V AC – 5SL4220-7RC

The Siemens 5SL4220-7RC is a reliable SENTRON miniature circuit breaker (MCB) designed for safe and efficient protection of electrical circuits against overload and short-circuit faults. It is widely used in residential, commercial, and industrial distribution systems for protecting lighting circuits, socket outlets, control panels, and automation loads operating on 240/415V AC networks.

This 2-pole MCB comes with a C-curve tripping characteristic, making it suitable for general-purpose applications with moderate inrush currents. With a 10kA breaking capacity, it ensures fast and safe disconnection during fault conditions, improving system safety and equipment protection. The compact DIN rail mounting design allows easy installation in modern electrical distribution boards and panels.
