The Siemens 5SY5215-7CC12 is a 2-pole miniature circuit breaker (MCB) from the 5SY5 series, with a C1.6 trip curve and a rated breaking capacity of 10 kA at 440 V DC. The C curve means it trips between 5 and 10 times rated current (8 to 16 A for this 1.6 A unit), suited for moderate inrush loads like small motors or control transformers in DC circuits.
Designed for DIN-rail mounting in control panels, this 2-pole MCB occupies two modular units (36 mm) of rail space. The 440 V DC rating makes it a fit for DC auxiliary circuits in industrial panels, such as DC motor control, battery-backed supplies, or solar combiner boxes where a C-curve characteristic is specified.
