The Siemens SENTRON 5SY7113-7CC is a 1-pole miniature circuit breaker with a C tripping characteristic, rated 400 V AC and 25 kA per IEC 60947-2. Under UL 1077 and CSA C22.2 No. 235, the rating is 5 kA — a different standard, not a derating; verify which applies to your installation jurisdiction. The 18 mm width occupies exactly one modular unit on a DIN rail, so it fits standard 18 mm-per-pole panel layouts.
Halogen-free and silicon-free construction, which matters in clean-room or semiconductor-adjacent installations where outgassing can contaminate optics or sensitive surfaces. Rated for ambient temperature from -40 °C to 75 °C, with derating on humidity: max 95% RH at 55 °C, tapering to 35% RH at 75 °C. That covers unheated outdoor enclosures and hot machine cabinets. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz — adequate for industrial machinery but not for direct mounting on high-vibration equipment without isolation.
Snap-on DIN rail mounting via the quick assembly system. Combined terminal top and bottom accept both busbar and conductor connections — no need to remove the busbar to wire the load side.
