The Siemens 5SY6206-7CC is a 2-pole miniature circuit breaker from the SENTRON family, with a C tripping characteristic rated for 6 kA interrupting capacity per EN 60898 at 400 V AC. It also carries a DC rating up to 72 V, so it can handle control-circuit protection on a 48 V or 60 VDC bus without a separate DC-rated breaker.
Combined terminal top and bottom means the same clamp accepts both the incoming supply and the outgoing load — no separate busbar terminal needed for the line side.
Rated 6 kA at 400 V AC per EN 60898, and 5 kA per UL 1077 and CSA C22.2 No. 235. The energy limitation class 3 means it lets through less let-through energy (I²t) than class 1 or 2 breakers, which helps with downstream component protection.
Operates from -40 °C to 75 °C ambient, with derating above 55 °C: max 95% humidity at 55 °C, tapering to 35% at 75 °C. Halogen-free and silicon-free construction — important for clean-room or semiconductor fab environments where outgassing contaminates optics or process gases. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz, so it holds up on machine-mounted panels near conveyors or compressors. Sealable design allows the panel builder to lock the toggle in the ON or OFF position with a padlock — useful for lockout/tagout compliance on a machine circuit.
