The C-curve (tripping characteristic class C) means the magnetic release activates at 5 to 10 times rated current, so it suits mixed loads with moderate inrush, like motor control circuits, contactor coils, or small transformers in a control panel. Rated 10 A at AC and 440 V DC, with a breaking capacity of 10 kA per EN 60898, it safely interrupts fault currents up to that level without cascading upstream. The 2-pole design provides simultaneous disconnection of both line and neutral in single-phase AC or both poles in DC circuits. The temperature derating table is worth noting: at 40 °C ambient the continuous rating drops to 9.39 A, at 50 °C to 8.74 A, and at 60 °C to 8.04 A. If this breaker sits in a warm cabinet near drives or transformers, size the load against the derated value, not the 10 A nameplate. The part carries an IP20 rating with connected conductors, so it belongs inside a closed panel — not in a washdown zone. The wide ambient range (-40 °C to 75 °C) covers unheated electrical rooms and outdoor cabinets in cold climates. ## Lifecycle and sourcing reality The part is also specified for railway applications (acc. to the design-of-product field) and carries the SENTRON brand. Approvals include EN 60898 and EN 60898-2 for DC breaking capacity. The pollution degree 3 and overvoltage category III ratings confirm it is suitable for industrial fixed-installation environments. ## Panel integration and mounting The breaker snaps onto a DIN rail (quick assembly system) and occupies 2 modular width units (36 mm total width). Mounting position is any, and the installation depth is 70 mm plus the 76 mm overall depth. The combined top and bottom terminals accept wiring from either direction, and the sealable design allows the panel builder to lock the toggle position after commissioning.","metaTitle":"Siemens 5SY5210-7KK11 SENTRON MCB, 2P C-curve 10 A, 10 kA","metaDescription":"Siemens 5SY5210-7KK11 SENTRON miniature circuit breaker, 2-pole, C-curve, 10 A AC / 440 V DC, 10 kA breaking capacity.
