The Siemens 5SL4104-7RC is a SENTRON 5SL series Miniature Circuit Breaker (MCB) designed for reliable protection of low-current electrical circuits against overload and short-circuit faults. It is a 1-pole, 4A rated MCB suitable for use in 230/240V single-phase systems and 415V AC distribution networks.
This device uses a C-curve tripping characteristic, making it suitable for control circuits, PLC inputs, relay circuits, and small inductive loads where moderate inrush current is expected.
