Siemens 5SL7216-7RC is a Betagard miniature circuit breaker, 2-pole, C-curve, rated 16 A at 415 V AC. Breaking capacity: 15 kA per EN 60898, 20 kA per IEC 60947-2. That 20 kA IEC rating gives headroom for industrial panels with higher prospective fault current — the EN figure is for residential/infrastructure branch circuits, the IEC one is what matters when you're coordinating with upstream switchgear in a factory distribution board.
Two modular width units (18 mm each) on a standard DIN rail. Sealable, halogen-free, silicon-free. Vibration resistant per IEC 60068-2-6. Ambient range -40 to 75 °C.
