It's designed for overcurrent protection of small motor feeders, lighting circuits, or control transformers in industrial panels where the load draws under 0.3 A per phase. C-curve handles moderate inrush — think small solenoid valves or contactor coils — without nuisance trips. The 4-pole frame gives three switched phases and a solid neutral (neutral switching is not active on this variant). Mount in any position, fits a standard DIN rail with quick-assembly fastening. Combined terminals top and bottom simplify daisy-chaining in distribution blocks. ## Installation notes Mounts in any orientation on 35 mm DIN rail. Touch protection is integrated — no need for additional finger-safe shrouds in most assemblies. Vibration resistance tested per IEC 60068-2-6: ±1 mm at 5-25 Hz, 50 m/s² at 25-150 Hz. Reliable in panels mounted on machinery or in mobile equipment.","metaTitle":"Siemens 5SY4414-7 SENTRON MCB, 4-Pole C-Curve 0.3A","metaDescription":"Active production.
