At 2 A per pole, this is sized for control circuits, signaling loads, or instrumentation supplies — not motor feeders. On a 24 VDC control bus drawing 1.5 A steady, the C2 holds fine; on a 0.75 kW motor, the inrush would push past the magnetic threshold on every start. ## Lifecycle and supply posture For a shutdown planner or MRO buyer, that reduces the urgency to stockpile — the part is still in the catalog and factory-supported. Standard 35 mm DIN-rail mount, 4 modules wide (72 mm at 18 mm per pole). The 3P+N format takes the neutral through a switched pole, not a solid bar — verify that your downstream neutral bar is bonded correctly if used in a TN-S system where the neutral must remain solid. Spring-cage terminals accept 0.75–25 mm² copper; torque to 2.5 Nm per the terminal marking.","metaTitle":"5SY4602-7CV MCB, 15kA Icu 400V 3P+N C2","metaDescription":"5SY4602-7CV miniature circuit breaker, Icu=15kA at 400V, 3P+N, C-curve 2A.
