The 5SL4204-6CC: The B-curve trips between 3 and 5 times rated current (12–20 A), which suits resistive and light inductive loads — think control transformers, lighting circuits, or small solenoid banks. On a 2-pole format you get both phase and neutral protection in one DIN-rail module, saving a slot versus two single-pole units.
